Fillet operation between two Brep models

[Fillet operation between two Brep models]

Hi Pay,

this is hard to say, without seeing the model. In general we always recommend to model in millimeter, because this will increase numerical accuracy, which also could lead to more stable fillets.

[starccm+ coupled with caeses on cluster]

Hi,

I think you need to provide the full path to the sim file. You can do this by using with the command getInputDir()/intake_optimization_0.762.sim.

[Closest distance between two surfaces]

Hi Rohan,

yes this is possible. You can create a shortest distance line:

[Clossing a surface]

Hi Gabriel,

problem is that you have a three sides face. So you need to collaps one edge. You can try to model the edge with a certain length and then use the a lofted surface with rails:

in the second step you can collaps the three points at the edge:

Hope that helps

Dear Sokykang,

Do you want to subtract the hull from a block inside CAESES or STAR-CCM+?

Hi Mingi,

can you try to put a space after the power command?

hmm does it help when you remove the complete friendship folder in %APPDATA%?

[Something is missing (3Dview etc)]

strange, then you should be able to create a new 3D window here

[Something is missing (3Dview etc)]

Hi Claudio,

can you close CAESES and then please go to %APPDATA%/friendship and delete the etc folder. After that the problem should be fixed.

[CAESES-STARCCM+ Integration and Surface Problems]

Hi Hasan,

 

usually we use the step Star-CCM+ export. I guess you are having a flow domain created with some Brep. Do you see any open edges there?

Hi Eren,

 

sure you can do this.

Hi Eren,

 

we have a tutorial here.

 

 

I guess it will be a good starting point for you.

[Modify .dat file imported from Converge CFD]

Hi Pablo,

 

you can import a surface.dat file into CAESES. It will split each boundary so that you have a trimesh for each boundary. This means that you can re-model certain surfaces and afterwards combine again with the rest of the original surfaces/boundaries. 

 

There is a tutorial on how to create a piston bowl inside CAESES. This will help you I guess.

 

 

 

best regards

[Data Point Import]

Hi Christian,

 

I cannot see the profile, since I don't have the text file. But I guess you would have to add the first point to the end of the objectlist again.

[Closing Brep Surfaces]

Hi, Michael,

 

you can also close the profile inside the feature definition, which we would usually do. The fin is symmetric as long you keep the camber value to zero.

Hi Michael,

 

find attached a version where the fin is modeled with a naca 4ds profile and a meta surface.

[Reverse Normal doesn't work with my Trimesh]

Hi Joseph,

I thought we have solved this problem from this post(https://www.caeses.com/forum/index.php?/topic/839-reverse-normals-on-trimesh-with-v44-doesnt-work/) by mail?

 

We always point the normals inwards for the converge export.
