Yes, you can. Finish the winio of the first window using:-

winio@(%lw[option], ctrl)
integer ctrl (output)

See the help file to explain how to use it.

Wilfried, I doubt very much that this is newly written code, it is almost certainly legacy code from the 70's or 80's when the use of IMPLICIT REAL*8(A-H,O-Z) was common place.

Where you assign values to FX as in FX(J,NRPM)=ABS(GENG(31,M)) the second index is fixed at NRPM so for the loop M=2,512 you are just continuously overwriting the same cell.

I declare element topology and nodal data as fixed size arrays in COMMON blocks. I have larger arrays than you are trying to use. So you could try using this method instead of dynamic arrays.

Jjgermis, this is what an advancing front mesh looks like in a simple square domain.

Hi Eddie,

Meshes composed of triangles are relatively easy to create. As John Campbell said, generating a quad mesh for an arbitrary multi-sided domain is no easy task! I wrote my own paver mesh ro ...
