calculation error

Post by red_armyy »

Hello

While i was doing calculation with code saturne with my mesh, which is composed with two different meshes, i got an error, when i opened the listing file to see this error i got this message :

/NEPTCFD/src/Code_Saturne_6.0.a_NEPTCFD_4.4.0.org/src/alge/cs_sles_it.c:5715: Erreur fatale.

Gradient conjugué: error (divergence) solving for Pressure

could you please help me to identify the mistake i did ?

Thank you

Hello,

Did you check the mesh quality, boundary conditions, and time step ?

Also check https://www.code-saturne.org/cms/documentation/BPG ("what if the calculation fails"), which is a bit old, but provides the general idea.

Regards,

Yvan
