Hello sdeb
\nthank you so much for your reply and it helped me a lot. But i have a problem where i am using overset model and now what i did that i define the motion on walls and for overset fluid domain i defined relative motion and UDF with only properties e.e mass, rotation and translation. Is this the right way to do it because when i define the same udf with motion on both then i get errors.
\n2nd thing is that i have attached the code below when i used my calculation for (#if !RP_HOST) and solving it parallel but in results i have variable output 6 times and every variable has a different value. If you can help me to get the one value which should be equal to the one we can see in dynamic mesh window. What i understood from manual that all variable values which i see in console are from different nodes and now i want to let them communicate so get the right value which i do not know yet.
\nAnd for writing a file with variables like time and velocity should i also use #if !RP_HOST or #if RP_NODE, etc.?
\nyour help will really appreciated. thank you.<\/p>\n
