  1. We can draw a number of curve and use FPolyCurve to fuse them into a "smooth" curve. An old post has discussed this question here. However, my model required a 2D "not smooth" enclosed curve made with three curves as below. It requires more than 2 intermediate points, therefore we can't use Multi Segmented Smooth Curve. And it's not a "smooth curve" therefore we abandoned the 2D interpolation curve. Therefore, I used poly curve, and results looks like this. To zoom in, we found flaws at top corners The flaws blocks me from moving forward in modeling. Get rid of the top line and the polyCurve seems work normal. My guess for the cause of the problem is the discontinuity, not a jump point but a removable discontinuous point. Please let me know if there is a way to deal with non-smooth multi-segmented curves. Any inputs are appreciated! WX

  3. Hi Hedi, thanks for the help. I tested the input files folder (generated by CAESES) and the error is that ./Allrun permission denied. After I gave the executable permission, it runs beautifully. Unfortunately, I did not find any post related to this issue on the forum. I tried run CAESES as admin (suggested in this post) but the same thing happened. I wonder if there is a way to give permission to the Allrun in CAESES. Thank you.
  4. Hello, I am very new to CAESES. I am following the video tutorial: sduct CAESES as openFOAM GUI. I am working on Ubuntu 14 with CAESES 4 and OpenFOAM 6. The Issue is: openFOAM scripts runs successfully with the STL generated by CAESES trimesh without the connection. I try to connect OF6 with CAESES4, hit RUN and the taskMonitors looks like this. Then I found a new directory of files copied. The Allrun also seems to run which generates empty log files. I do not find any result file, in this case, folder named "500". This is the Allrun: blockMesh > blockLog surfaceFeatures -overwrite > surfaceLog snappyHexMesh > snappyLog simpleFoamShear > simpleLog #post processing postProcess -func 'patchAverage(name = sduct_lightpink,p) ' -latestTime >pin.dat case.foam *************************************************************************************************************** I was not able to upload the project file to the forum. But I am more than willing to provide it via other methods. I really appreciate any help! WX
