To Richard:

I usually copy an input to test some changes in geometry and parameters. Right now I have an input that I don’t know how but any time I change something and try to run it I get error 175. Can you help me to solve this?

regards

Santiago

Your file ran fine for me in Version 5.10.

What Version of CAESAR II are you running and did you create this file on this same Version?

One thing you can try to resolve this is the following:
- Enter the Piping Input module.
- Move this input Window aside, and start Windows Explorer.
- Go to your data directory and delete all of the files associated with this job EXCEPT for the _A and _J files.
- Go back to the Input Window and try to run "batch".

I'm using version 5.0 and I have just tried the following:

I have deleted all files but _a after that I opened the input and run it. I ran ok, but then I made some changes like pipe dimension and tried to run the input. The again error 175.

That doesn't seem right. Send the model to techsupport@coade.com with some instructions on how to reproduce this. We'll figure out what's going on.
