Abaqus

is there any command available to skip/suppress the element quality check, while running an analysis in abaqus?


 

Nastran SuperElement

I would like to use condensation to calculate the normal modes of
a structure. These grids are connected to the structure through RBE3 (master
grid). Let me know if there's a way to use the master grids of RBE3 elements in
the A-SET?

the error form the f06

GRID

DMIG (superelement)

i would like to condense the model (superelement) using Nastran (PARAM, EXTOUT, DMIGPCH). 

but, i'm having few CONM2/CELAS1/CBEAM elements at condensation locations. i would like to know these (CONM2/CELAS1/CBEAM) elements will create any issue while condensation 

DMIG

can i include mechanisms while creating DMIG in FEA?

Pressure Load in Abaqus

In Abaqus, *DLOAD element set, Pn, magnitude.

What does "n" in "Pn" mean?

buoyancy

Can i say, the center of buoyancy and the center of gravity of the immersed part are same?

FEA

How to include water buoyancies effect in analysis for an abaqus model. The abaqus model is developed using shell and solid elements

 

FEA

Using Abaqus, hanging some mass in Truss element (T3D2), facing numerical singularities and lack of convergence due to Truss elements have no initial stiffness to resist loading perpendicular to their axis. If a stress-free line of trusses is loaded perpendicular to its axis in Abaqus/Standard. Kindly suggest me how to overcome this. 

FEA

I want to model wire rope/sling as 1d-element in abaqus.

let me know the suitable 1d-elemet for wire rope/sliing.

FEA of Crack Propagation

Hi all,I'm a student of of Madras Institute of Technology, Chennai.I'm trying to do stress intensity based crack propagation in metals. I’m using Abaqus/CAE. I’m following the abaqus 6.5 documentation, I have completed upto Contour integral evaluation,” (Section 7.10.2). but I’m unable to proceed further, since “Crack propagation analysis”, (Section 7.10.3) refers only “Input file usage” (Not Abaqus/CAE Usage)I hope someone can help me
