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

unable to find rpvar 'velocity'

for each input parameter countless times. After it finishes trying to find them, it gives this error

Error: floating point exception
Error Object: #f

Hope you guys can help. Thanks in advance!

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
