Try to create the report as html instead of .doc and see if it works.

Yes, that is the only was to analyze them using beams. Otherwise you can use solid and/or shells.

Hi, You have the option of creating just the mesh in CFW before running the analysis. I would suggest using this to make sure that all the features are properly resolved by the mesher after you make changes to the model. If the automatic mesh settings are not resolving the solid & fluid regions...

Make sure you have read/write access to the temporary directory. Also check that the working directory is not full (where the TEMP and TMP environment variables point). If this does not work then repair the installation of SW/COSMOS.

Yes, Results --> Surface Plots. Better way is to set up a surface goal before the analysis.

Have you tried a time dependent analysis with output options specified to save the initial results? I don't think the iterations are related to real time in a steady state analysis.

reilly22, i did exactly what you have described here and couldn't reproduce it. i see the values for the sensor locations after using Probe in the feature manager. i'm on SW/CW 07 SP2.

This function has been in CFW for quiet sometime. It is described well in the documentation and there is a tutorial too. The documentation and tutorails are not in the most accessible place. Look for these in a folder called 'lang' in the FloWorks installation folder.

If the geometry is symmetric then model 1/2 or 1/4 of the geometry and use symmetry BCs to constrain the model.

Greg, I'm not sure I understand your post fully.......would you elaborate on it a bit more?

Thanks for your replies. The area at the base is not large, the legs are made of tubular steel. I will apply the BCs as described by John and see how the model behaves. Appreciate your inputs!

I have to analyze an assembly very similar to a stool (4 legs welded to a flat plate) and was wondering what is the best way to apply restraints without using symmetry. The legs can spread out but cannot move vertically. I can restrain UZ but what about UX & UY? I'm using 2nd order tets for...

Have you tried using the Bolt Connectors? For this you'll have to include the part that the flange is bolted to. This part can be approximated by a simple plate with a large EX if it is not critical. There are always going to be high stresses at the restrained nodes.

the first iteration in FloWorks usually takes the longest time. also, FloWorks is very RAM intensive. be careful about the no.of cells that are generated. in general, for a 1GB RAM machine the no.of cells should be below 250,000. try running the analysis without any refinements first.

when you plot the mesh on a 2D plane do you see this component resolved properly?? if the component is not resolved then the flow would go right through it. if the component is thin as compared to other components then you might have to specify the min. wall thickness or use control planes for...
