Hello everyone,

I am a new user for ANSYS. I am trying to simulate the modal analysis of the section of pipe by ANSYS Mechanical APDL 14.5.

But I got the problem about ... How to make the couplings as the attached picture? 

I need to set the same condition of each pair of node on the right (nR) and the left (nL).

Thank you very much

Yours sincerely,

I am looking for good documents for writing generic macros. Can anyone direct me to efficient learning and uses of macros.

I am trying to find the area of selected elements ( the model which has only mesh and no geometry ) by command in ANSYS apdl.
Is there any *get command getting that area of elements.
Thank you

I am looking for details on Ansys .out file. ( like CRITERIA calculation, force convergence and displacement convergence )
Any details nomenclature on the .out and .err files would be very helpful.

Hello,

I am trying to figure out how to incorporate Z-mat files in ABAQUS to simulate complex constitutuve models of polymers. While I have worked with UMAT subroutines before Z-mat is something new. Can somebody explain why Z-mat is necessary and are there any differences between conventional UMAT/VUMAT and Z-mat files?

Thanks.

Hello there!

I was thinking to use inverse distance  interpolation technique as a finite element shape function. However, I am not sure about its performance for finite element method, inverse distance interpolation was originally developed for geographic information system.

can anyone help me please?

thanks in advance!

hello

i have this model on Abaqus "in the attached photo" and i want to add a solid material in the gaps between those cubes and assign material properties for it

how can i do it ?

is there a function in abaqus which can do that

thanks

not able to edit ABAQUS/CFD 6.10 input file
the keyword for an abaqus/cfd model cannot be edited
???? any suggestion???

Hello everyone , 

LAMMPS suggests a script to calculate C44 , C11 & C12 .The question is : How to calculate the others for a nanomaterial ? Thanks in advance ! 

How to model Fastners in Abaqus? I have an assembly which are connected by more than 500 fastners and has angle and channel sections? 

hi guys. i am analyzing a 2d truss with abaqus and i need the nodes displacement and axial force along elements. now i have displacements but i tried very hard to find axial forces and no luck. it's the first time i use abaqus and i am learning it. i have searched alot in internet but i found no answers. and here it is my last hope. does anyone know how i can get axial forces for 2d truss in abaqus??  i will be very thankful.
