Re: 2D-meshing in cfd

I do slightly differently, I don't know why: I can have access to the boundaries directly in the first node of Paraview Openfoam reader. After I do the same operation than in the tutorial and finally I integrate over the surface of interest the lift and drag forces, but I think that I have to multip...

Re: 2D-meshing in cfd

Hello, After compute a 3D case, in which I have boundary layers sub mesh regions, I have only access after Extract Block command to "multiblock datatest and internal mesh". I cannot choose the boundaries of interest like in the tutorial you show me. What should I do in FreeCAD to have access to the ...

Re: 2D-meshing in cfd

Thank you very much for your help. I see also some add-on workbench on the forum. https://reho.st/self/cf1b9abce60c5280c3b476be82b30fe86f130cb9.jpg Is these tools are usefull for the post processing ? I install the workbench DesignPhysics, but I don't know how to put it visible on the FreeCAD window...

Re: 2D-meshing in cfd

Thank you, it works with gmsh but no boundary layers are avalaible with gmsh. Only refinement on surfaces but I don't see any change in the mesh when I use or not these feature. Now I want to try to calculate the lift and drag force acting on a surface ... Seems difficult, I start with your post on ...

Re: Post processing tools

Thank you thschrader, Ok I have test it, is a simple and good solution for incompressible flow. I try to compute a compressible flow case but I have some error. Is the volumic mass data available in Paraview for compressible mass flows calculation? https://reho.st/self/6fdeab5974a08cc778f18800ef0312...

Post processing tools

Hello,

Is there any macros or patches to calculate for example the mass flow rate ?
How do you proceed ?

Sorry but i have very few experience with openfoam

Re: Heat transfer simulation with cfdOF

Thank you for your answer, It is planned to add solid parts for heat exchange also ? If yes good news. What is an approximative time schedule ?6 months 1year or more? I have a second question. Is it possible to add post process functionnalities to compute the flow rate, etc ? It seems tricky to calc...
