Hello, i'm trying to use UDF for charge density of inert particles. I'm using MHD module and DPM.
When using discrete phase sample on reports (particle tracks for example) i see error:
Error at Node 2: get_udf_function: function charge_density_macro has wrong type: 2! = 46.

It happened even with simple code like i used last time:

#include "udf.h"
DEFINE_DPM_PROPERTY(charge_density_macro, c, t, p, T)
{
real charge_density;
charge_density = -1;
return charge_density;
}

I know, error means that i'm using wrong type of udf for this parameter, but i wonder what i do wrong...
P.S. If i use interpreted , here is no mistake. That erroe happenes only when i use compiled code (i need to use compiled for main code)

I've compiled this code without any error

Are you sure you can define negative density?
