Re: no mehs_output

Hi Yvan,

Thank you so much for your kind help . It now works. But I have one more question. What's is the different between the cs.solver and run.solver? In this case I can got run.solver, but no cs.solver......

Re: no mehs_output

Hi Yvan, Thank you. You mean mesh_input can be used as followed on archer? if domain.param == None: domain.mesh_input = "../MESH/mesh_input" domain.partition_input = None domain.restart_input = None I have set domain.exec_solver to false in the user_scripts.py . But it still didn't works. ...

Re: no mehs_output

I'm sorry Yvan, I can't get your point. :cry: :cry: Because the code_saturne on archer dosen't support the format of Cgns, So I need to get the mesh_output in my own computer and make it as the mesh input on arhcer. The problem is the mesh_output didn't exist. So how can I get that? I have tried pre...

Re: no mehs_output

Hello Yvan, I think it's because the mesh is not modified, as I change another mesh, the file mesh_output can output. The problem is that I used the file attached to restart the case on archer: if domain.param == None: domain.mesh_input = "../MESH/mesh_output" domain.partition_input = None...

no mehs_output

Hello Everyone,

I am modeling a case a simple aerofoil. But the file of mesh_output doesn't output, which I need used as mesh input on archer. I don't know why. I attached the setup.xml and listing.

Thank you for your help.

All the best, Yany.

Re: divergence in turbomachinery module

Hello Yvan, Thank you for the reply. Yes, you are right . The rotation zone is not exactly a circle. I modified the mesh today. However, the issue still exist after about 10 iterations. I uploaded the new mesh and setup file. ROTOR: https://www.dropbox.com/s/jmwu1vzdbogwb7k/ROTOR.cgns?dl=0 STATOR: h...

Re: divergence in turbomachinery module

Hello,Yvan, If you have time could you please have a look at my case? I'm really appreciate that. I 'm working on that nearly one year. The mesh is simple with good quality. I choose turbomachinery module of transition but after some time steps, the error file output: Error in turbomachinery mesh up...

Re: divergence in turbomachinery module

Hello Yvan , Thank you. I will try to improve the time step. There is no diverge shown on the listing file, but the maxmum velocity is so large. I check the result in Paraview when I choose transition_coupled. and found the problem on the interface of rotor and stator. The figure shows the pressure ...

divergence in turbomachinery module

Hello everyone, I used turbo-machinery module for the wind turbine with version 5.2. First I run it in the steady mode. Then I added the turbomachinery module. I tried full transition , transition-couple, frozen and frozen-coupled mode. However the calculation cannot converge. I choose a very small ...
