Hi sir I have a small doubt in nx nastran. i.e when I connect two components with bolt connection with spider elements iam getting huge stress on spider connect nodes because of shear load. For same model when I take glue connection stress are very less(because two components are connected with...

Hi I have to do the static analysis in nx nastran for a big model. So i solved the model I got more stresses on one plate on the model. So iam trying to reduce the values by adding stiffness. While solving I came to know that 'by doing super element analysis it is very easy'. I did the...

when i wanted to give contact between surface and solid it shows the fatal error FOELCF and no contact is formed.

Thank you for giving your valuable suggestions. In my model I don't have any element errors and you said that 'there is a chance of errors' so what type of errors' it may have. And one more doubt is what is massless mechanisms.iam using nx12

Hi, When I wanted to run sol 109 direct transient analysis in nx nastran the message showing that 'during detection of massless mechanism the number of singularities found 6435 which is greater than NLMAX 60, increase the value NLMAX.' in solution monitor. However I got the solution file but...

Hi, I wanted to give Sol 109 direct transient analysis in nx nastran. I know in femap but I didn't understand how to give time history data in nastran. Please tell me the detail steps.

Hello sir, In nx nastran unexpectedly if we delete the result file(op2) can we recover that?
