Hi all, I'm a newbie to use OpenFOAM. I want to simulate a flow in control valve to measure its Cv, as steady and incompressible conditions. I set the pressure at inlet and outlet, and I want to get the velocity of flow and so the flow rate. I create a simplefoam case, I imported the mesh from...

No one could help me?

Hi all, I'm trying to do a simple simulation with CATIA. I have a beam with two pivots on two double-end holes: there is no restrain for rotating around axis hole. A distributed force (2000N) acts perpendicular to the hole axes. I hope the image attached helps to understand. The problem is...

You're right, but I reduced at the minimum the inlet speed but I didn't find a convergence. Actually I don't understand what are the equations at the base of this solver. Could you explain me?

Hi all, I'm trying to solve a simulation of mixing elbow with OpenFOAM. I used the classical configuration of elbow template found on tutorial folder of OpenFoam. When I launched simulation it crashes after increasing time and I got this: Time = 0.25 Courant Number mean: 2436.58 max: 20540.4...

Sorry, open my mind

Ok, but if I do not select Part Body, it seems that I apply force only on solid face without surface created in the solid face. It is correct? Or in this manner I apply the force to all solid face?

Ok, I undestand. You selected Part Body in the tree. It's correct to say that in my previuos manner I apply force only out my surface? Thanks

Hi, I don't undestand the difference!

Hi, I try as you explained. But in this manner I can apply forces only out of this surface extracted. I need to apply forces in. Where is my error? Thanks

No other methods? There is not way to get pdf3D from CATIA?

Hi all, I use CATIA V5 Generative Structure Analysis module. I need to know how to apply a force on part of a bigger surface. For example if I have a cube, I need to apply a force on a quarter of one of six faces. How to set this? When I select a face it aplies force on all the surface. Thank...

Hi all, I have a doubt on FEM analysis conducted with Generative Structure Analysis module of CATIA V5. If I leave 1 DOF (one rotation) on a part, but the equilibrium is done by balanced forces which I impose, can I solve FEM analysis on CATIA? Or it need to set 0 DOF on a part? If I leave 1...
