Good day

I've been trying to import the results of a water hammer event into a model in CAESAR II in the drop-down menu:

Tools > External Interfaces > AFT IMPULSE

The problem is that when I try to open the .FRC archive created in the AFT Impulse, after select the nodes where the forces are to be applied I get the error:

forrtl: severe (64): input conversion error, unit15, file D:\...

Image PC Routine Line Source libifcoremd.dll 002C33B6 Unknown Unknown Unknown

This is happening in CAESARII versions 5.2, 5.3 and 7.

The units of the .FRC file are seconds and LB, the same settings of my CAESARII files

Could you help me with this issue? thank you in advance.
