"Floating point division by zero" in Structural Module

Anonymous — Thu, 09 Nov 2017 22:59:15 GMT

I am running a simple one span slab girder with 2018. When I run the pretensioned beam analysis the results to the transfer condition are calculated and displayed but the other loading conditions are not. I do get a message that says the perimeter can not be calculated. I also get an error message of floating point division by zero and and external exception 80000003. The graphics also freezes up. Is there a plug in that I need to install.

Hi there

Can you zip up the model file and upload it to the forum so I can run it through at my end?

Here is the file. I am evaluating the software and started with this simple single span slab girder.

Thanks for your help.

I've found the cause of the error message. The problem is caused by the small amount of cast in place concrete you've added in order to satisfy the requirement for there to be cast in place concrete defined. This 0.5" square section is not touching the precast beam. If I offset the cast in place concrete by -0.65" in the x direction, the error goes away. I will record a defect for this issue.
