Dear RG NELSON, 1/- the "FlexPDE help" gives very few informations about the way to use the 'fixed point' facility in 2D problems; where this 'fixed point' must be written in a program (I have tried in BOUNDARIES but error message arise due to the following line : LINE TO (x,y)...) ? In my case, I have no specific boundary condition on this 'fixed point' because a singularity arise at this point and I just want to have a mesh node at this coordonates. 2/- I also need to have the calculation of an ELEVATION calculation at a point (as it can be easily done on lines using FEATURE facilities). Is possible? Thank You very much indeed, especially for the 'TRANSFERMESH' modification in the last version. KAPLAN |

1. FIXED POINT(x,y) is syntactically equivalent to START(x1,y1) LINE TO (x2,y2) You should be able to put it almost anywhere within a REGION of the BOUNDARIES section (but not before any REGIONs, or the parser will reject it). 2. I'm not sure what an "elevtion at a point" means. A plot frame with a single dot on it? Why not just use a REPORT on some other plot to report the single value? Or in a SUMMARY page?
