I agree with Zebra,
this is pretty well documented in the online help. Take a close look at that.
Make sure you got your folders set up properly: you need a sub-folder "femdata" and "results" within the folder with the batch file.[font=Courier]
FeFlowBatchFolder
+ BATCHFILE.BAT
|- femdata (with your FEM files)
|- results (for your dar/dac files)[/font]
This is what a line in my batch files typically looks like:[font=Courier]
feflow -run -work "C:\FeFlowBatchFolder" -log "feflow.log" -dar "model.dar" "model.fem"
feflow -run -hide -exit -work "C:\FeFlowBatchFolder" -log "feflow.err" -dac "model.dac" "model.fem"[/font]
For details on the different options, type "FeFlow -help" in a DOS window and you'll get a summary of all the options.
For this to work, the FeFlow folder has to be included in your PATH variable (which I think is the case by default).
Any folder or files names containing white-spaces (blanks) need to be enclosed in quotes! I do that for any file and folder name, so I don't forget by accident.
Good luck! Chris
