fortran exp domain error Prince, West Virginia

Why would a variable (array Y) that worked fine before suddenly begin taking on values that reach infinity, thereby crashing the SQRT function? But I don't call function sqrt explicitly in my program. code in 3rd party library) contains a STOP statement. my program was written in F77(some part)and F90(some part).

the original test case to ensure numerical fidelity. Thank you. Sign up for a free 30min tutor trial with Chegg Tutors Dismiss Notice Dismiss Notice Join Physics Forums Today! How can I check this?

Check for type/kind mismatch (CMPLX (0.0d0, 1.0d0) may not do what you would expect). An author of several well established and highly successful computer books, Prof. It's also possible the previous run had the same problem but wasn't flagged so you have, in fact, uncovered an heretofore unknown error. However, during execution, the program choked on a certain line in one of its many subroutines- a line which involved SQRT. 3 key lines are as follows (real U is passed

Since the error message mentions "sqrt" the likely cause is that you are taking the square root of a negative value (for instance) without allowing for a complex result.

You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. Can I try any declaration tricks to "stabilize" Y? For example, the following statements generate this error: result = sqrt(-1.0) // C statement result = SQRT(-1.0) ! assist.
