    Femap API Error "Type mismatch"

    i'm not too versed in the C API, only femap's native BASIC and the python API, but what line is giving you the type mismatch? also it seems this is not the full code, but an excerpt

    Data surface pressures on either side of surface

    Of course they can be summed 'easily'. I mean that, because one side of the surface is loaded in all its area, while the other side is only being partially loaded, care must be taken with the data surface interpolation. If the CFD and FEM meshes are very different, it could lead to...

    Data surface pressures on either side of surface

    After runnin similar tests for the followig geometry: The results are similar to the previous tests. The drawback is that the pressures cannot be easily summed together. Because of the interpolation, different mesh geometry between CFD and FEM, and different CFD mesh for each surface, you'd...

    Data surface pressures on either side of surface

    After checking the applied force vs reactions, I actually realised I made a mistake when inputting the data surface with the summed pressures, I entered 9.5e-4 instead of 9.5e-5. I corrected the issue and re-run the tests, and now all 4 methods check out correctly. While this was a great find...

    Data surface pressures on either side of surface

    I did the tests you proposed, and I got some wild results. I performed a total of 4 different tests: 1- Apply load on elements, each pressure on a different data surface, selecting face 1 or 2 2- Apply load on elements, using a data surface summing the pressures on each face 3- Apply a load on...

    Data surface pressures on either side of surface

    Hi karachun Thanks for the post. I think the case of a billboard under wind load sounds like a fitting aproximation. This is a quick sketch: You can visualize it as a CD, where the 3rd surface woul be the edge itself. I will try the simplified test, hadn't thought of that. Fingers crossed...

    Data surface pressures on either side of surface

    I have some pressure data coming from a CFD analysis. After reading through the multiple posts here and watching videos on youtube, I was able to mostly apply the pressures to my model in a coherent way. I'm having trouble regarding a specific area of the structure, however. In the CFD...
