Hello, I am running a simple curved sandwhich panel with large displacements on. the boundary conditions are : it is pinned on one end and allowed to translate on the other.I have applid pressure to the inner surface of the beam. It is a non-linear analysis and i am not able to get it converged...

is there any free software that i could download from the net to import a parasolid model into abaqus.Thanks

I wanted certain nodes at certain location in my model so i went ahead and created nodes at these locations. But when i mesh the surface the nodes which i have created are not connected to any of the elements. Is there a way in femap to create elements such a way that the nodes are used to form...

I have used spring element as panel pins in my analysis. But when the .nas file is written it is generating CROD card instead of CELAS2 card which is meant for spring elements. Even the spring property that i have defined is not generated. Can anybody tell me why this is happening. Thanks.

is there a way nastran can caluclate the centre of gravity for the whole model because i want to apply my loads at this point and i have planar model.Thanks.

Suppose i slice a solid and then would want to delete that slice or partition i created. how do i do it? all i could find was delete>solid because delete curve does not work.Thanks.

Hello, I am analysing a sandwich panel as a plate and trying to corelate the displacment and stress with theoretical solution. I ran the analysis and the displacments conforms well with the theoretical solution but not the stresses. I don't understand why it works this way. i am comparing the...

I have a 3d- square box structure which is pulled frm one end and fixed the other end. Suppose I want the internal loads or the nodal force along the interface i.e; edge connecting one side to the other..how do i get it? I understand that the total nodal forces or the total internal load would...

how do i rectify the singularity error.is it got to do somethign with the boundary condition?

Hello everyone. I have to define a local co-ordinate sytem in my model. Wjat i did was modified the material angle. is that the right way to do? by default would i be getting all the stresses in the local or global direction? if i get it in global how do i get the results in the local...
