    Riks analysis

    What I notice is that this is avoid by using a larger load in both the buckling and Riks analysis. So instead of using 1 N, I can use 1000 N and avoid the problem. I find this odd. I've used nlgeom, but the step before analysis of buckling I did not understand. Do you mean that I should run a...

    Riks analysis

    Hi, I'm doing some buckling analysis of a simply supported plate. I've ran linear buckling analysis to find the eigenvalues and used the lowes eigenvalue in a Riks analysis to seed an imperfection. But I expirience some wierd things. If I seed my imperfection to 1, the analysis complete and I...

    Analysis does not start

    The problem is that there is no error file. The job is submitted, but never starts running. It just stays submitted for ever. Senad

    Get node coordinate

    Hi, go to Tools - Query - Point/node and pick the node you want the coordinates for. You have to be in mesh module. Regards Senad

    Analysis does not start

    Hi all, I'm expiriencing some problems when submitting job in Abaqus 6.8-1. The job is submitted but wont start running. Anybody else had this problem? Never happend in 6.6-1 or 6.7-1. Regards Senad

    Abaqus crashes when seeding

    Thanks for answeres. I would agree with you pettervu, it mostly happends when I seed many regions, so there may be some rules about edge choise. But I've noticed that this rarly happends in 6.8-1. Regards Senad

    Buckling mode of I-profile

    Hi all, I'm running a simple buckling analysis of a simply supported beam to determine the eigenvalues. I've used a I-profile on my beam, and the results are odd. Seems like there is no continuity in elements close to the load I have no problems if I do this with a rectangular profile or a box...

    Dummy question about abaqus

    Well, I have really never worked with composite layers in Abaqus, but for me it seems like something is wrong with your mesh/element type. If you go to visualization, you can check witch elements are causing this problem in the element nodeset. That may help you find out what the problem is, but...

    Dummy question about abaqus

    What kind of elements are you using? I think you have to use different type of elements, elements with more nodes and integration points. For example if you are using 4-noded shell elements, y ou have only one integration point, while 8-noded elements have 4 integrations points. Regards Senad

    Parent/children features in part module

    Thanks for your answere corus. So this is the best way of doing it. I figured I also can cut the feature I want to delete, but maybe your suggestion is better. Regards Senad

    Parent/children features in part module

    Hey all, is it possible to deleta a parent feature whitout deleting its children features in part module. I have a lot of features in my model, and if I change or delete one of the, the rest fails to regenerate. Does anybody know a way to avoid this? Kind regards Senad

    Abaqus crashes when seeding

    Hey all, Abaqus CAE often crashes when I assign seeds to the model. Has anybody else expirienced this problem, and do anybody know if it's possible to fix this? Kind regards Senad

    Elements missing proparty defenitions

    Thanks for a quick answer. This is probably a stupid question, but where do I find the set you are talking about? Senad

    Elements missing proparty defenitions

    Hey all, I have made a part from shell and solid elements and when I run the job I recieve this error: "Error in job PPA_0_0: 169 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection". Probably some of the regions are not assigned...

    Importing parts to abaqus

    Hey, I've imported an IGES file from ANSA to ABAQUS/CAE. The result is an invalid part. I've tried to repair it with geometry repair tools, but it dosn't work. Do anybody know which is the best file to import (for parts) and how I can make the part precise and valid? Kind Regards Senad
