Hi Pay,

Just wanted to let you know this bug is fixed in the next update.

[Windows Server 2019 dll missing error]

Hi Nikolas,

ok - is TCAE executing CAESES? It could be that it propagates its environment to CAESES or  runs CAESES with the bin-dir as working directory (which I don't think).

You could try to write a batch-script that runs CAESES with a modified environment?

Cheers,
Stefan

[Windows Server 2019 dll missing error]

Hi Nikolas,

There is no special CAESES distribution for windows server. The installed version should in principal run fine.

Does CAESES (crt) starts when you run it standalone (i.e. via start menu)?

It looks as if the environment when running caeses includes the TCAE bin directory which leads to the error (Windows resolves external libraries in this path which is wrong - at least for CAESES).
You might try to either remove the TCAE directory from %PATH% (in the system environment) or supply CAESES with a different environment when it is started by TCAE.

Cheers,
Stefan

[Syntax error in new version 4.1.1]

Hi Bram,

 

Is this code snipet inside a function? We have disabled the scopewise notation inside functions due to technical reasons so you could simply write:

 

imagecurve interpolCirccurve()

 

interpolCirccurve.Setcurve(Curve)

interpolCirccurve.setDomain([0.5,1])

interpolCirccurve.setName("halfCurve")

interpolCirccurve.SetVisible(0)

 

Does this help?

 

Cheers
Stefan

Hi Chris,

 

Currently only Windows and Linux are supported.

[Change License ID / Account]

Hi Michal,

 

Simply start CAESES (reset license selection) from start menu and apply for a new license.

[BREP to NURBS surfaces]

Hi Antonios,

 

Breps are basically a set of trimmed surfaces that are stitched together. These cannot easily be transformed to nurbssurfaces.

Think of a surface with some holes - there is typically not a single nurbs representation for this type of geometry.

 

Cheers,

Stefan

[optimization_caeses with starccm]

Hi Mohamad,

 

There is no connection to either the geometry or the starccm setup for the used designvariables (pm1, pm2).

So when the designengine is doing the variation, only the values change but nothing more happens.

 

You have to modify your setup in a way that changing a designvariable leads to a changed geometry.

Checkout the sample "S-Duct Geometry Variation".

 

Cheers,

Stefan

[The full model can not show up]

Hi Yanxin,

 

The project units are set to kilometers. If you set it to meters, it schould be ok.

(to be changed in staus bar -> project units)

[Exporting Volute Geometry from CAESES to ANSYS]

Hi Nitin,

 

This is difficult to say without a sample of data / the project you try to export.

What is the original format you try to export?

[Objectlist cast to self-made Feature definition]

Hi Bram,

 

using the typename (F3DPoint, FFeature::...) will create a reference (a different name and optionally a casted type) to an existing object like:

 

point p(1,2,3)

F3DPoint myRefPoint(p)

 

// myRefPoint is p

 

same for features:

fp_... f(...)

FFeature::... myRefFeature(f)

 

Cheers,

Stefan

[Objectlist cast to self-made Feature definition]

Hi Bram,

 

you have to use the typename in the first place like:

 

FFeature::CurveFunctions dd(MyList.at(0).CastTo(FFeature::CurveFunctions)

 

Cheers,

Stefan

[passing value and object between features]

Hi Hamidreza,

 

You could create an instance of FeatureNo1 in your project and pass it as argument to 2, 3 and 4. Once it is up to date it would not run again.

Simply create an argument of type FFeature::FeatureNo1 in 2, 3 and 4.

 

Best regards,

Stefan

[paste data from clipboard]

Hi Hamidreza,

 

Ok, now I understand. Currently there is no option to get the clipboard text.

However, it would be possible to offer this function in the next release.

 

Would that help?

 

Cheers,
Stefan

[paste data from clipboard]

Hi Hamidreza,

 

You can use 

 

FDesignResultsTable.countRows()

FDesignResultsTable.countColumns()

FDesignResultsTable.getValueAt(row, column)

 

to access the values of a results table.

 

something like:

 

loop(myTable.countRows())

  int row($$i)

  loop(myTable.countColumns())

    int col($$i)

    double value(myTable.getValueAt(row, col))

    // ...

  endLoop

endloop

 

Cheers,

Stefan

[large batch of offsets transfer to bspline]

Hi Chang,

 

You can simply use a loop inside a feature.

Please check the example for reference.

Hi Alvaro,

 

I just want to inform you that this issue will be fixed in the upcoming version (4.2.1).

[Lines in Breps after using Polysurface]

Hi Bram,

 

just a short note from my side:

There is a difference between BrepSources and BooleanOperation / SolidFromIntersection.

 

In the boolean operation, we add the source surfaces of the polysurface to increase robustness. This is maybe not in all cases the best solution and we will think this over.

But then we would need to introduce "split continuity" in all these tools (like in BrepSources) - simplicity vs. options ;)

 

Cheers,

Stefan

[Remove gap between two surfaces in the model]

Hi Amin,

 

What format do you need for export? 

 

If you need an STL, you should use a trimesh to triangulate the surfaces and close the gaps.

 

I did this in your project, see if it works for you.

 

Cheers,

Stefan

[Ubuntu 16.04: Segfault when moving mouse in 3D view]

Hi Philipp,

 

the crash is probably due to the graphics driver / hardware. In the terminal output you can see that no valid openGL context could be obtained from the system.

We sometimes see poor driver support under Linux OS for integrated graphics (Windows too).

 

You shoud try to find install  a prorietary / vendor driver (probably intel?) for your graphics system.

 

An alternative could be to use a dedicated graphics card (nvidia preferable in my personal opinion). You would have vendor support and a much better performance even with a cheaper card.

The integrated graphics is dedicated to desktop / office use, CAD is not really the idea of these things ;)

 

Cheers,

Stefan

[IGES/IGS export settings]

Hi Harry,

 

Have you already tried to read an IGES file exported by CAESES in NAPA? Have there been any Problems?

 

As far as I know, all surface types are exported as type 128 and breps as trimmed surfaces. Maybe you can take a simple hull model and export it as surfaces and as well put the surfaces inside a brep and export the brep to see which works better (you can also set the tolerance at the brep but this setting might introduce problems in the brep itself).

 

Unfortunatly I do not have NAPA, so I can't try it myself but I an most interested in the results.

 

Cheers,

Stefan

[IGES/IGS export settings]

Hi Harry,

 

Currently there are no additional setting for the IGES-export.

Could you tell us a bit more about the needed IGES specification and what software you try to use. Maybe we can do something ...

Stefan

[Dynamic Commenting of Template Files]

Hi Brit,

 

I attached a simple project where I use a feature to return a string depending on an input value.

You get simple line and block commenting by using this as value of entries.

 

This should do the job.

 

Cheers,

Stefan

[Installation CAESES in ubuntu 15]

Hi Aldi,

 

Great to have you on board.

 

In order to install CAESES on Linux you simply have to unpack the installation package to a destination of your choice.

Check out CAESES_Product_Registration.pdf in the unpacked folder for further instructions.

 

Cheers,

Stefan

[Caeses and VTK]

Hi Max,

 

You are right, CAESES can read different kind of VTK formated files (XML, legacy, ...).

Did you try to connect via "File -> Data Connection -> VTK"?

 

What is the error?

 

If you could attach a small example of the kind of data to process, I can take a look into it.

 

Cheers,

Stefan
