    Femap output types.

    It's very hard to answer to your question. I guess you to look for a good book with practical examples because the correct answer depends on many parameters. The quickest answer is : all the result postprocessing is useful for get the correct response. If the results change small when you look...

    Riks analysis

    Yes. The buckling analysis is a linear pertubation analysis, so if you evalute a preload structure the results could be different. Bye minoand

    Riks analysis

    The post buckling analysis is very sensitive analysis. Do you try to take a step before analysis of buckling with a load of 90% of the first eigenvalue analysis of buckling not preloaded ? Remember to active the nlgeom parameter to on. After this, you can use this new values for imperfection...

    Error message list

    Some know I can get a list of abaqus error message with possible solution ? I cannot find any solution for : ***ERROR: Issue cannot be deleted Not all data Released. Thanks, Minoand

    How to get Nodes Associativity in Femap

    You can create a group with curves you want to look for associativity. Then you can add to this group the node associated with curve using "group - node - on curve" command. bye Minoand

    2 materials

    You can display the elements in element set ErrElemMissingSection in visualization tools to understand the problem. Try it and tell me the result. Minoand

    calculation models coefficient

    I know that the better way to characterize a rubber it is possession of the esperimental data. However, do anyone know the values maximum and minimum of calculation models coefficients (C10, C11 Neo-HOOKE model, for example) for the different kind of rubber ( natural, NBR, HNBR, etc) ? Thanks...

    Change parameters units

    I didn't explain my problem well. Example I had to make a cube 1CM x 1CM x 1CM and I insert the parameters 1, 1 and 1. I checked solidworks unit and I saw that the unit is mm. If I change to MM solidworks change the parameters to .1,.1 and .1. I don't want this, I want to change unit from MM...

    Change parameters units

    This option convert the cm in mm and the model dimension don't change. Probably is not possible to do that I need. thank, Minoand

    Change parameters units

    I made a solidworks part with parameters in cm. But soliworks part is set to mm. Do someone know a method to multiply all parameters for 10 ? I don't want to use the scale feature but change all parameters values. Thanks for the answer, Minoand

    Tetrahedons

    It's true, if you compare a bricks and tetrahedons model with the same DOFS. If you use parabolic tetrahedons model with elements much smaller than in a bricks model the response is different. The use of tetrahedons are very usefull because you can use automatic mesh to generate the model. So...

    shell elements

    I know the limitation about ratio of the tickness and the model dimension( > 1/10). Does someone know if exist a limitation about the ratio of the tickness and the minimum element dimension ? Thanks, AM
