Hi

I would like to switch from an elastic analysis in ANSYS to a damped vibration analysis. What are the important aspects to consider in the new analysis? What is the analysis to be done, in ANSYS Workbench?

I thank you in advance


Best regards,

Give some thought to picking only one of the three analyst types you're going after. For any of them you'll be very clumsy and inept until you learn how to reconcile the ANSYS results with basic theory and practical results. It's hard enough for linear static analysis. If you have any analysis skills at all (you weren't clear on that) it's going to be a difficult job both formulating the problem and error and validity checking. The only way is to start simple and develop a checking and troubleshooting methodology as you go. Best to start with a problem you've already done some other way.

Don't get discouraged when everything you do seems to be full of errors. The most useful skill you'll ever need with ANSYS is figuring out how your simple analysis produced meaningless garbage and  what to do about it. The only indispensable tool you'll ever have is a solid background in fundamental mechanics.
