Hello, I managed to define square cells using vc3d in prostar, turn off all the equations and using sormom I can solve the equation for Sudoku grid using a reference book. You just need to inverse a matrix and remove the square that are not possible.

I used the known numbers as boundary conditions that I can access via posdat.f

save the geom file, save the problem file, run and I have the solution in 3.45 sCPU time!

I submitted my solutions before everyone from problem in the newspapers and the internet. I won $2,450 in a week, which will go toward paying my star-cd license.

Excellent!

thats awesome, any chance of the coding, i could do with some spare cash!
