  1. python: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory AcuConsole requires the standard C++ libraries, version 5 to be installed on the system. These libraries can be downloaded from the various rpm repositories on the web.
  2. If User's are unable to open a database or if it gives an error like "Unable to create path Marker" then we can say that the database is corrupted. In such cases the data from this corrupted database can be extracted by following the below steps, Install HDFview on the machine (http://www.hdfgroup.org/hdf-java-html/hdfview/) Open HDFview GUI Load the database by clicking on File > Open in the menu bar and navigating to the database location. Select the database and click Open All the data in the database will be displayed in hierarchical format Click on first item in the tree, press Shift and select the last item. All the items in the tree will be selected Right click and select Copy Click on File > New > HDF5 Provide a filename (eg: test.acs) and save the database Scroll down to the bottom to see the new database created (test.acs.h5) Right-click on the new database and select Paste. Click Yes to copy the selected objects You can see all the objects under the new database Save the database. File > Save, then close the HDFview GUI by clicking on File > Exit Rename the new database (eg: test.acs.h5 to test.acs) Load the new database into AcuConsole
  3. For a given element (except for the fifth node of a pyramid) each node is connected to three other nodes via three connected edges. Assume R1, R2, and R3 are the vectors for the three connected edges. For a positive Jacobian: ( R1 × R2 ) · R3 > 0 This test is done for every node of every element - so a mesh with 10K tetrahedral elements would yield 40K Jacobian tests.
  4. Hello When importing a nastran file into HyperMesh I find warnings as shown in the image Can you explain to me where these warnings come from? and how to correct these errors? Thank you
  5. During the processing stage, acuPrep determines whether or not 'surfaces' from Simple BC or Element BC commands are boundaries or internal to the parent element set. If a surface element (tri or quad) has a volume element on only one side - or volume elements from different sets on both sides - it is considered to be a boundary. If a surface element has a volume element on both sides, and those volume elements are in the same element set - it is considered to be internal. If there are surfaces in the geometry between volumes in the same element set, these surfaces should not have Boundary Conditions defined. If there truly is an internal 'wall' (such as a baffle) within a given volume, the mesh surfaces should be split to yield two sets of nodes and two sets of surface elements.

    WARNING 510: Imaginary part of the impedance is large thus the real part will be inaccurate WARNING 4722: It is highly recommended to use double precision accuracy (solution settings) WARNING 509: Reactive power large thus real power is inaccurate WARNING 2340: No further output of warnings and hints Hı, I have these problems and I don't know how I solve these. Please help me
  7. Hello guys, first of all, I'd like to thank you for your great support. I'm quite new to FE analysis and now i'm facing my first problems. To get known to HyperWorks, I started to mesh an imported CAD file with Hypermesh and defined materials and properties. Before applying Boundary Conditions and forces I wanted to check the model for errors and started the anaylisis ( Solver: Radioss (Block 140)) That's where I encountered some error messages. With the help of this forum I was able to fix some problems. For these messages I wasn't able to find any solution: According to that warning, i found a thread here ( http://forum.altairhyperworks.com/index.php?/topic/19028-warnings/#comment-39612 ) Unfortunately I couldn't help myself to fix that issue. For which criteria I have to check the surfaces? What's to do to fix that error in element group? Regards
  8. Hi, I am using Incremental Radioss. There are few default material available in the database. When running the simulation with those default material, the simulation runs successfully (though it has 0 errors and 2 warnings. The warning is related to the material property). But I am using a different material which I add it in the database manually. When running the simulation with the manually added material, I get the error in simulation running or the simulation gets stopped in the middle while it is running few animation files. In the summary page, I get 0 errors and 2 warnings, the same one which I got while running with the default materials. The difference is that, the simulation gets over when running with the default material but it isn't getting completed with the manually added materials. The material I am adding is DP1200 steel. Have attached with the screenshot of the error. Error : 2 warning id :1084 Warning in material law1 When referring to material law1, it says it is related to the elasticity of the material. But I have given the input values properly. Kindly help me as soon as possible and thanks in advance.
