    CORRECTING THE TIME INTERVALS IN ABAQUS

    FrankZephr, Please attach .CAE or .inp By looking your previous model, I recommend u to change some parts 1. I think you should have large deformation in this model, so please change static, general type of step to Dynamic Explicit 2. Pay attention to the step you specified for the boundary...

    Plotting and CFD Pressure input

    Ramin, There is no good manual for FSI, I just asked you because I saw you are familiar in CFD. By the way, u can attach your .inp. GOOD LUCK

    Plotting and CFD Pressure input

    Ramin, If you would like to have a contour of the deformed object go to result> deformed variable , also it is maximum and minimum spot of deformation can be shown (countor option> limitation) About your next question, the simplest way is creating a table based on .txt file for each nodes and...

    CORRECTING THE TIME INTERVALS IN ABAQUS

    Hi Frankzephyr, I have some suggestions, 1)set the minimum time increment as it is suggested by abaqus edit step> incrementation tab 2)Pay attention to the type of step u mentioned, static/ dynamic explicit ...., are you sure it is suitable for your simulation? 3) refine your mesh (make it...

    3D elements are shown like two shell surfaces!!!!!

    Many thanks for your comments. @IceBreakerSours: I'm not using any display group. The interior space of my model seems empty, just its borders are shown!! My model is attached @Akabarten: When using below/above cut, the interior space seems empty. And in the case of using ON CUT, the cutting...

    @Prab: you use student version of abaqus. Follow jobs> write input then attach .inp file. @IceBreakerSource: Many thanks for your helpful suggestion in this forum. I'd be so grateful if you could take a look at my question in forum. I really need an expert to help me. TNXS

    Maximum stress on a surface

    Hi, For whole parts, the easiest way is to contour option> limits>show location. Good luck, Mahsa Ghaffari

    Hi Prab, Regarding the magnitude of gravity force, it is better to take advantage of "body force" to represent the gravity force. However, to make the magnitude of a force constant you should create a table, such as t(0)= force, t(timestep)= force (Do not use ramp option). Good luck, -Mahsa Ghaffari

    3D elements are shown like two shell surfaces!!!!!

    Hi guys, I have a problem in showing my model in abaqus. I used 3D element to show some layers but whenever I cut my model it is shown like two shell layers with a space between them!!!! I need its picture for my paper but I don't know how to create it. Its pictures are attaches. Thank you in...

    Brain to Skull Interaction Property

    I'm doing the same project. Based on the new papers, CSF is modeled between the brain and skull and none of them is modeled without consideration of CSF. Thus, I think that it is would be better to create CSF and use cavity filled method in Abaqus, It is really new for traumatic brain injury...

    An unknown message has been encountered!

    Dear IceBreakerSours, Many thanks for your help in this forum. I found that in order to limit such jumps in pressure and get accurate result, I must add damping features to my model, in which the stiffness matrix multipler is assumed 0.001. When I add this value to the model. The runnig time...

    Maximum relative displacement between two nodes during the explicit analysis

    Hi, I'm looking for finding a way to detect and extract maximum relative displacement between two nodes during the analysis, could you please help me to find a way to get it? Many thanks, -Mahsa Ghaffari

    Hi IceBreakerSours, Many thanks for your response. In fact the problem is with the graphic of my PC. and I could solve it change ATI driver. BTW, I really appreciate your help :-) If you let me I'd like to ask you some questions about getting result. I'm looking for the way that abaqus create...
