Re: Error with Catalyst postprocessing

Hello Yvan,

One more question about Catalyst. It is possible to update the python script during the simulation, or once the simulation start the script is read only at the initialization of the writer?

Thanks.

Regards,
Luciano

Re: Set listing verbosity options

Hello,

In order to reduce the size of the listing file you can try modifying the verbosity level with the variable iwarni or changing the output frequency with the variable ntlist or change it in the GUI in Output control -> log frequency.

Luciano

Re: Volume of Fluid (VOF) CS6.0_beta

Hello,

You have to set using user functions and you don't need to recompile CS. When you add an user function in the SRC directory it is compile when you launch CS.

You can check in the listing if VOF is activated.

Luciano

Re: Volume of Fluid (VOF) CS6.0_beta

Hello,

To activate VOF you have to set the variable ivofmt = 0 using the cs_user_parameters.f90 routine and the void fraction is store in the ivolf2 array.

Additionally, you can check this post
