    Exhaust Manifol Thermo-Dynamic Analysis

    Hi to all Abaqus People, My project is to investiga the thermal stresses on a exhaust manifold. The test try to duplicate in abaqus consists two different boundary loads one is thermal cycle and other one is the vibrations from the engine. I try to do it in abaqus coupled thermal displacement...

    How to skip the element check in abaqus ?

    Hi to all experts, I have another hot topic for you !!! I have a question about the element check in abaqus. When i run a model done by another person i got an error message like ErrElemVolSmallNegZero this is because of element quality. It is ok so far but they claim that it is possible to run...

    Stress at integration points or at nodes ?

    Think of that you have a 3-D model and you simulated some forces acting on it. And get a Stress contour ? it should have normally the most accurate results at integration points (or not)? but then you have 4 integration points so should we extrapolate the results to the nodes ? or for this...

    Base motion

    Hi to all, My problem is to give base excitation to a part in two point and with different directions and magnitudes. Is it possible to do that in abaqus ? Can i give 2 different base excitation to the system in modal dynamics?

    Bolt modelling

    Hi to all, Nowadays we are trying to model bolts by using beams instead of solid modelling them. My question is how can i apply pretension force to the beam element in abaqus or in hypermesh ? do you have any opinions about bolt modeling with beam elements and pre tension. I wanna to find an...

    multiple processor

    Hi i would like to ask if it is possible to use multiple processors for modal analysis in nastran ? and if yes how ? i have a PC with 2 double core processors. Can i use mutiple processor with sol 103 ?

    excessive stress after bolt pre-load step in abaqus simulation

    hi to all We are try'n to make a thermal analyze aprox. 15 cm long heavy exhaust Manifold head and part of engine block where the part is attached. Problem that we encountered recently is excessive preload at the bolt neck. In the model we have pre-load at the middle section and bolt is...
