Problems with UDS_UNSTEADY
 
Hi,

I want to change the unsteady term in the UDS transport equation because I want to transport a number of particles in my multiphase model. Does anyone has experiences in using this macro ?

Thanks Julia

I've managed to work this out. Post what you want to change it to and I'll post back the *apu and *su terms.

Dear Greg,

I need the original term without the density and I tried it the following way

*apu = -(C_VOLUME(c,t) / dt)

dt is the time step I have defined as a global variable.

Thank You in advance Julia
