UDF DEFINE_SPECIFIC_HEAT after loading - fluent closed automatically

EvaKn · December 31, 2020, 06:13

Hello,

I have a Problem with a UDF for specific heat.

I can built and load the udf and in the Material Dialog I can choose the udf.

Now when i want to assign the udf, it loads briefly and right after that fluent closes automatically. Why does this happen?

In the UDF I also define density, sound of speed, thermal conductivity and viscosity with DEFINE_PROPERTY - this works perfectly...

How can I fix this? Do I have a Mistake in the UDF?

only the DEFINE_SPECIFIC_HEAT part

eth-cpL.c

Thanks in advance for the help!

are you using any UDM in your UDF?

remove line

Code:

T = C_T(c,t);

from your code, T is defined in header
