Simple problem, what's the solution?
Problem statement:

1) According to PHOENICS ENCYCLOPEDIA, to define fluid and solid in the solution domain, PRPS is used. FIINIT(PRPS)=value for domain fluid and SOLID is defined by INITIAL PATCH like as follows:


According to this, PRPS for fluid does not give required result as I set by FIINIT(PRPS)=value

2)But if I use two separate INITIAL PATCH of PRPS for both fluid and solid, it gives corrects result.

so, why don't I get correct result by step 1?

any suggestions....:confused:

Did you check the value of the "INIADD" boolean command? Is it set to "F" or to "T"?

It may help ....

yup, I checked. INIADD=F that means value of domain fluid region will not be added to solid region.

I also try with INIADD=T. In this case PRPS of SOLID adds the value of PRPS of DOMAIN FLUID. but PRPS for fluid becomes incorrect.... :(
