If youhave concerns about an analysis, we suggest that you contact us at an early stage, since it is usually easier tosolve problems at the beginning of a project rather than trying to correct an analysis at the end.Please have the following information ready before calling the technical engineering support hotline, andinclude it in any written contacts:Your site identifier, which can be obtained by typing abaqus whereami at your system prompt(or byselecting Help-On Version from the main menu bar in ABAQUS/CAE or ABAQUS/Viewer)· The version of△ BAQUS that are you usingThe version numbers for ABaQUS/Standard and ABAQUS/Explicit are given at the top of the data(. dat)fileThe version numbers for ABAQUS/CAE and ABAQUS/Viewer can be found by selectingHelp-On Version from the main menu bar.The version numbers for the abaqus Interface for MoldFLOW and the abaQus Interface forMSC ADAMS are output to the screenThe version number for ABAQUS for CAtIa V5 can be found by selecting Help-AboutABAQUS for CaTiA V5 from the main menu bar in either of the aBaqus for CAtIA V5workbenchesThe type of computer on which you are running ABAQUSThe symptoms of any problems, including the exact error messages, if anyWorkarounds or tests that you have already triedWhen calling for support about a specific problem, any available abaqus output files may be helpful inanswering questions that the support engineer may ask youThe support engineer will try to diagnose your problem from the model description and a description ofthe difficulties you are having. The support engineer may need model sketches, which can be sent via fae-mail, or regular mail. Plots of the final results or the results near the point that the analysis terminated mayalso be needed to understand what may have caused the problemIf the support engineer cannot diagnose your problem from this information, you may be asked tosupply the input data. The data can be attached to a support incident in the aBaQUS Online SupportSystem. It may also be sent by means of e-mail, tape, disk, or ftp Please check the ABAQUS Home Page(http://www.abaquscom)forthemediaformatsthatarecurrentlyacceptedAll support incidents are tracked in the abaQUs Online Support System.
