How to let UDF run in parallel
 

Hello I have the below UDF for mixture density it works fine in series I want to run it in parallel what changes I need to add.

include "udf.h"
DEFINE_PROPERTY(c_densityN10RaT1E6, c, t)
{
real rhm,rho,To,Co,betaT,betaC;
real T = C_T(c,t);
rho= 1.12;
Co=0.049;
To=313.15;
betaT=0.0032;
betaC=0.590636677;
rhm = rho*(1.-betaT*(T-To)-betaC*(1.*C_YI(c,t,0)-Co)); /* density of mixture */
return rhm;
}

Thanks

Parallelization
 

Usually, such code do not require parallelization. However, you can do that just to be sure.

Put whole of the code within

#if !RP_HOST
#endif

#if must be after opening brace of the DEFINE_ function and #endif before the the closing brace.

Many thanks Vinerm to the reply. Is that used normally with interpret option or I need to use compile when using parallel?

Parallelization
 

Compilation or Interpretation are not related to parallelization. So, if you are using the code for parallel simulation, you should parallelize it, doesn't matter whether you compile or interpret.
