Hi guys,

I am running a dynamic mesh with an UDF and trying to use input parameters through scheme just as described in here.

The problem is when I run the simulation, the first time step runs fine but as it goes to the second time step, Fluent gives me
Code:
unable to find rpvar 'velocity'
for each input parameter countless times. After it finishes trying to find them, it gives this error
Code:
Error: floating point exception
Error Object: #f
Hope you guys can help. Thanks in advance!

AlexanderZ will become famous soon enoughAlexanderZ will become famous soon enough
why do you use scheme variables for parameters?

there is a macro RP_Get_Input_Parameter("variablename") for UDF

by the way, it is impossible to understand the reason of your problem without your detailed description of steps which leads to this error

best regards
