Recommend Visualization software for FVM

zonexo

hi,

i'm looking for a easy to use visualization software to visualize the data i obtain from the FVM code. I was using tecplot but it doesn't seem to be very suitable. there also seems to be some errors when i try to interpolate the values when using cell center display.

since i'm using fortran, i hope the data format isn't too complex. it should preferably be able to show cell center and node center values at the same time.

of course, if it's free that's even better....

thanks alot!
