I currently use DesignSpace V5.X with SolidWorks and generally found it very easy to use. I carried out a comparison of the same part on ANSYS and DesignSpace, and found the results to be close - the main differences were mainly due to the fact the model had to be greatly simplified for the ANSYS model - fillets etc.<br><br>If you are working with thin-walled parts that are very long then DesignSpace seems to have a problem, however, DesignSpace is capable of analysing assemblies.<br><br>As far as I know, you are allowed a 30 day trial with DS - might be worth obtaining a CD and seeing what it can/cannot do.<br><br>Regards
