    VALUE FOR PARAMETER NSET CANNOT BE MORETHAN 80 CHARACTERS

    Open .inp in a text editor (I usually use the CONTEXT EDITOR with ABAQUS HIGHLIGHTER). Then go to FIND. Type NSET Check whatever is after the '=' symbol Proably it's too long, so you'll have to rename it to a smaller name, and then change all references to the older name to the new one...

    Stress Strain Data for Rubber Modeling

    Dear ME7, Just one thing. You're thinking in making a linear approach of the material data? You've have to be careful with it, because as the dog bone is made from rubber you should use a hyperelastic approach. Let's say, you have: FORCE vs DISPLACEMENT you can obtain STRESS vs STRAIN (where...

    Unrealistic Displacements in Frequency Studies?

    Just to complete what Corus've said. No matter which software you're using in MODAL STUDIES (FREQUENCY), the results are: - When the models reachs its natural ressonance; - How it would behave in ressonance; So we have: - WHEN: is the frequency (in rad/sec or Hz) resulta - HOW: is the deformed...

    Heat Exchanger stress analysis

    Dude, You can do this by two ways: - Run a Flow Simulation Analysis and export the results in a static analysis; - run a thermal study (available from SolidWorks Simulation Professional). Best regards, Eduardo

    running abaqus keywords in CAE

    I've never done this in AbAQUS CAE, I usually call ABAQUS in a CMD.EXE window and then follow the solvers in PROCESS of TASK MANAGER and in the .dat, .log and .msg files opened in CONTEXT TEXT EDITOR or NOTEPAD. Hope this can help you, best regards, Eduardo

    How to remesh a model

    *Step, name=Step-1, nlgeom=YES, inc=100000 *Static 1., 60., 1e-20, 60. try running with a SMALLER increment! And you have two options, try using 360 instead of 60 or converting it do RADIANS! Best regards, Eduardo

    Problems with units in Abaqus

    Dude, The scale factor cames with the model (geometry) input you've done! About the units, ABAQUS "doesn't" consider wheter units you're using, so the results are in the units you've input. As an example, I usually want the STRESS results in MPa [N/mm^2] so my units input should be: PRESSURE...

    !!TOO MANY ATTEMPTS MADE FOR THIS INCREMENT!!

    You could run it with ABAQUS EXPLICIT and in material set the MAX STRAIN of the material for deattaching elements (as you can see in a machining analysis)! By the way, for accurate results in this case, you should use a GREAT QUALITY MESH!!! Best regards,

    How to carry out analysis in Abaqus on an imported Hypermesh file.

    NewFriend, Usually when I use a pre-processor, I do export a input file of ABAUQS (after finishing the pre-processing), with FILE-EXPORT-ABAQUS INPUT. This Input I shall edit the card (using a text editor as CONTEXT!! it's free and has a hoghlighter for ABAUQS CARDS), modify anything htat's...

    restarting an analysis

    Hello Oriol, Just copy the input files for the new computer and restart the analysis! (remeber that any reference to folders of the former computer shall be re-directioned for the new folder and locations on the new workstation!). Best regards, Eduardo

    Hyperfoam vs Hyperelastic

    Dude, You shouldn't check the model type only for the value range of the poisson's ration. You've viscoelastic models with poisson in order of 0.49 (rubber under high tempeartures). Check the comportament of the material you're trying to model, if it at high stresses it has huge deformations...
