• Sergio, I'm not too familiar with the CXX cards. It appears that some parameters have been added to the original one. Can you please add a brief explanation to each one of the cards describing the parameters? For example what are the values unde…

• Sergio, Thanks for the update. Solution now makes more sense. Would you please add pretension to the assembly as you suggested. I'm unsure how to add the pretension. Thanks again.

• Sergi, In your fixed model posted earlier I realized that both symm_1 and symm_2 surfaces in the Named Selections are assigned to 230 faces. Could you please explain how you came up with these numbers and how would you handle a more complex 3D cyc…

• Sergi, Initially from your reply, I thought the first model (on the left) was my model. That's why I raised a question of software version. Please discard my first reply. However, after further investigation of both models I realized that my mo…

• Sergio, Thank you for your review. I downloaded your model and ran it without any changes and got the exact results as my original model. What version of the Mecway did you run My install is at 12.0 64 bit.

• Sergio, This is great work. Thank you! I resolved the convergence issue by Replacing “contact” to “bonded contact” for bolt head in my original model. Thanks to all for sharing and contributing your support, specially Victor.

• prop_deisgn, How did you add fillets to the model? Did you FreeCad software? Thanks

• prop_design. 1. I am trying to model/analyze a bolt connect assembly to predict stresses around the blade holes. In your simplified version you have removed all the bolts/nuts and that's representative of my model. Can you suggest a solution to my…

• Those are weak springs suggested by Victor. Appreciate your support.

• Sergio, Just to make sure I understand your approach. First I should assign thermal expansion coefficient in the material properties for bolts only and then select the nodes on the bolts and assign temperature under New Loads and Constraints. Is th…

• Sergio, I’m not an expert in Mecway to add thermal expansion coefficient to the bolts. Do you have a sample or link on how to do this? Thanks
