use serial processor to open
 
I noticed this happened to me when I imported a mesh from a grid generator besides ICEM.

I had to start FLUENT with the serial processor in order to import the case file from pointwise. Then after that, I would be able to save the case and reopen in FLUENT with parallel processors.

Hope this helps.

I have the same problem...what did you mean with 'open UDM in the DEFINE menu' because I am using in define_mass_transfer function C_UDMI but it doesnt work in parallel...

thanks in advance!!!


Hi,
He meant that if you have UDMs in your UDF, first, you'd better check if you have defined them in Define menu or not. You might have forgotten to define them before you use them in your UDF. That's all.

Actually the divergence is strictly related by the dpm injections, for the cases including dpm injections.

If you go on injecting DPM in an unsteady manner, dpm allocates memory and at some point the anlysis crashes. kind of a memory error.

switching of the unsteady dpm can solve the problem, but by this way some accuracy may be lost.
