pressures in MDM - parallel fluent
 
Hello,

I have a problem:

I'm running an unsteady analysis of an oscillating wing using the moving and deforming mesh feature. I'm running the parallel version of fluent and I would like to export at each time step the pressures on the wing surface.

I tried using the export feature, ascii mode, but it doesn't work for parallel version of fluent.

So I tried to write an UDF function to export the pressures, but again In parallel mode I cannot write the pressures on the surface wing....

Is it possible to write an UDF function to write these informations?

Regards,

Hi,

In this kind of problem ,we have to do re-coding to write values . In paralle, there are some nodes and host. Ordinary coding doesn't divide this nodes or host and this thing makes a problem.

So this writing process has to be done in the host. In UDF, RP_NODE, RP_HOST is defined. Details of this macro is showed in the UDF User's Guide.

Thank you

FJ
