Hi I need a function for node stretching in two sides of a line. Would any body can refer me to a source (prefer accessible on the net) to find it. Any comment is appreciated. Thanks.

can you clarify your need further? Do you want a function that makes node clustering at the two ends of a line?

Hi Shahbazi,
There are many ways to do that. you can use any function for example a parabolic function and choose your dx based on that. I have put a file in my homepage using hyperbolic tangent stretching. This can cluster either on any one of the sides, at the center, or at both the sides (which is what you want). You can access the F90 module at: http://www.lkt.mavt.ethz.ch/~chidu/onedgrids.f90 Let me know if you are unable to get the file. best, Chidu... |
