Re: Meshing warning

Thank you Luciano, The little experience I see the account apparently, launch the case and converge, my mistake maybe was to guide me a lot by the visualization in para view and not address the problem separately. So far everything is going well and the simulation is delivering values ​​according to...

Re: Meshing warning

Thanks Luciano, I have occupied a time step of 0.08 and of 0.01, if I decrease it the simulation time increases too much, with a time step of 0.001 the simulation time is approximately 30 days for which this solution makes me unfeasible, proble with another geometry and a higher time step where the ...

Meshing warning

Hello, Dear I am having problems with my mesh for a simulation of flow on a sphere, the case diverges. . The number of courant reaches a value of 600 and the visualization in paraview tells me that the problem with the mesh is in the vicinity of the sphere, I have tried to follow several recommendat...

Basic question

hello, I'm using cs to simulate a flow on a sphere, I've had some problems for the simulation since the cases diverge, I'm occupying the k-epsilon turbulence model for this. my question is. It is possible to simulate the flow with a fixed speed?, in which option do I determine this speed? in profile...

problems with boundary conditions

hi, I'm working on a simulation of an air flow on a sphere inside a wind tunnel but I am having some problems at the time of the simulation. the error message is First face with boundary condition definition error (out of 15000) has boundary condition type 0, center (0.475, 0.1485, 0.00155) cs_bound...
