    Errors in ABAQUS Composite model

    Now I get the following warning: Solver problem. Zero pivot when processing D.O.F. 1 of 22 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_1_1_1_1_1.

    Errors in ABAQUS Composite model

    By refining the mesh it appears that the aspect ratio warning no longer appears, I will see if the model functions now

    Errors in ABAQUS Composite model

    Thank you! I decided to cut the layers with "offset faces", did a solid homogeneous section and just added orientation with "Assign Material Orientation". That seemed to solve the errors but now I get the following warning: The aspect ratio for 960 elements exceeds 100 to 1. The elements have...

    Composite material properties

    The software doesn't have a lot of documentation, I'm having a hard time searching it and also I thought xt xc yt yc were supposed to be in Pascals, I don't know where the mm come from

    Errors in ABAQUS Composite model

    Hi! Currently I'm modeling a composite, however, the following error appears: ***ERROR: 48 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection. ***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE...

    Composite material properties

    Hi guys! I'm modelling a 20 ply composite and I want to assign the properties, however I'm not familiar with them. I'm working with Simlab and when I put the composite option, these are the properties that I have to use : Can someone tell me what exactly does this mean? And also how do I add...

    *** ERROR # 1000 *** in the input data: in Simlab

    Thank you! Apparently the error was in the step, currently it's working.

    *** ERROR # 1000 *** in the input data: in Simlab

    Hi! I'm doing a coupled thermal structural analysis and these errors show up: *** ERROR # 1000 *** in the input data: Incorrect data in field # 3. Expected INT > 0 or blank, found INTEGER (0). *** ERROR # 1000 *** in the input data: Incorrect data in field # 4. Expected REAL > 0 or...

    Export fem file from Hypermesh

    Hi! I imported an Abaqus inp file to hypermesh but I want to export the file in .fem form but it hasn't been able to do it. Anyone has any tips? Thank you

    ABAQUS/CAE JOB IS RUNNING SLOW

    I added contact control and that seems to keep the top surface in place. However, the results were excessive with the von mises results being up to e+4, I showed my boss at my internship and he said that I should change the body heat flux to a surface heat flux for more accuracy and he also made...

    ABAQUS/CAE JOB IS RUNNING SLOW

    With the U1 and U2 fixed, the singularities disappear but I notice that the top surface moves away from the bottom, I don't know if it's a problem with the contact. I tried ticking the "tie ajusted surfaces" box but that creates excessive distortion warnings.

    ABAQUS/CAE JOB IS RUNNING SLOW

    No, how do I eliminate that? Right now the only BC that I have is a Displacement/Rotation with U3=0 in the bottom face of the larger body. In step time it went till 0.000155 on the last increment.

    ABAQUS/CAE JOB IS RUNNING SLOW

    My job aborted after 207 increments, the error messages were: Time increment required is less than the minimum specified The analysis has been terminated due to previous errors. All output requests have been written for the last converged increment. The warnings were: For contact pair...

    ABAQUS/CAE JOB IS RUNNING SLOW

    For the heat flux I just realized that I did add one. I'm trying to mimick an autoclave process. For this I needed the model to pass through different temperatures at different times, to achieve this I added an amplitude, with the time being in seconds and the amplitude representing the...

    ABAQUS/CAE JOB IS RUNNING SLOW

    After enabling parallelization and changing the density the job ran much faster but the job aborted at the 50th increment, which was my maximum, should I increase the maximum number of increments? The only warnings I got were the warnings that I already talked about.

    ABAQUS/CAE JOB IS RUNNING SLOW

    The job is still running, it's been going for 3 hours, there's 16 increments so far and there are no further warnings. I didn't use parallelization. I don't remember adding heat flux, I added an initial temperature of 20 Celsius. Thanks for telling me, I will change the density.

    ABAQUS/CAE JOB IS RUNNING SLOW

    The warning messages are: For contact pair (assembly__pickedsurf14-assembly__pickedsurf13), not all the nodes that have been adjusted were printed. Specify *preprint,contact=yes for complete printout. Surface interaction intprop-1, associated with one or more contact pairs with surfaces having...

    ABAQUS/CAE JOB IS RUNNING SLOW

    Hi guys, Right now I'm running a coupled temp-disp analysis in ABAQUS/CAE, however, my job is very slow, 15 minutes have passed and only 1 increment has been made, I tried modifying the step to a time period of 1, maximum number of increments of 50, initial increment size 0.01, maximum 1 and...
