    Fred,<br>
     typically a floating point error is some unhandled error in the
    Fortran that causes the DLL to crash; trying to take the log of a
    negative number, dividing by zero, accessing an array with an index
    that is either too big or too small. The only way to really track
    down the cause is to run the simulation from the Fortran compiler.
    Please feel free to send me the *.tpf and any files I need in order
    to run it and I can have a look for you.<br>
    Best,<br>
