In Apache Sim calculation I received this error:

"Runtime error from program:c:\program files (x86)\ies\ve 2012\apps\apache.exe

can anyone help me with this error.

Thanks

sometimes the codes on these errors can give clues if you can relate them back to keywords in the model (sadly I don't have a lookup table for this task), I'm thinking SHDRTF could be something to do with the shading file.

access violation, failed to write to location could be related to where the project is saved.

I have only some general advice on it

- check where the model is saved, if on a network or area you don't have full read and write permissions then save to somewhere you have full control like your C: Drive. Check the properties on the project folder to ensure not set to read only.

- check you have plenty memory available when running the sim, close any memory intensive applications you might have running at the same time

- check the quality and robustness of your geometry. Since this might be linked to the shading file then you should reassess geometry quality (ModelIT Settings menu >> Model... >> Check) and also maybe take a critical look at the complexity of your shading bodies. It could be difficult to identify the problem (iteration being my only strategy) but try rerunning with no shading and if the sim runs then you at least know you're going in the right direction.
