Re: Problems with mpi on Ubuntu 18.04

Hi Yvan, I think I may have solved my problem. I removed two of the sticks of RAM in my computer and I received no errors after running several simulations in serial or parallel, or with CS-4.0.1 or CS-6.0.2. I swapped the two sticks of RAM with other two sticks and I regularly got crashes. I ran a ...

Re: Problems with mpi on Ubuntu 18.04

Dear Yvan, I'm not sure why Code_Saturne was using multiple threads. I didn't specify for it use multiple threads and it only appeared to be happening when running valgrind. When I recompile Code_Saturne with --disable-openmp, it only used one thread when running with valgrind. I ran 6 computations ...

Re: Problems with mpi on Ubuntu 18.04

Hello Yvan, I'm still experiencing solver errors when trying to run a computation. I tried running Code_Saturne on Centos 8 and I ran into the same troubles that I had with Ubuntu 18.04. I also upgraded to v6.0.2 with a simpler case and I still had errors with the solver and preprocessing stages. Wi...

Re: Problems with mpi on Ubuntu 18.04

Dear Yvan, I will check the code_saturne.cfg file. I tried compiling Code_Saturne with both --with-mpi and CC=mpicc but the problem occured with both. When I installed mpich, I completely purge the openmpi package and recompiled my Code_Saturne installation, but I will double check that openmpi was ...

Problems with mpi on Ubuntu 18.04

Hello, I have been trying to install Code_Saturne v4.0.1/v4.08 on Ubuntu 18.04 and I have run into some mpi issues. I compiled it with the gcc and openmpi ubuntu packages along with libxml2. Running cases in serial mode, my Code_Saturne installation runs fine. However, in parallel mode my simulation...

Re: Mesh Joining Problem with Turbomachinery Module

Hi Yvan, The mesh upstream of the interface is completely normal to the interface. Downstream of the interface, towards the impeller, the angle of the mesh differs slightly from 90 to 75 degrees. With 90 degrees being normal. Cell size in the normal direction to the interface is 0.0004. The aspect r...

Mesh Joining Problem with Turbomachinery Module

Hello, I have been trying to join two meshes with the transient turbomachinery module for the past week, but I can't get past 10 iterations before there is a mesh joining error. I made sure the interface of the two meshes matched and the mesh was equally distributed in the theta direction. In the ra...

Re: Wall BC with Transient Turbomachinery Module

Hi Yvan, After spending more time on this problem, I believe the problem is unrelated with the compressible module and is a bug with the turbomachinery module. When the BC are updated in the navstv routine (line 762 and below), the boundary coefficients are recomputed if a wall function is being use...
