Hi, I have two contacting surfaces around 200 mm^2 each. The surface normals are uniform and have the outward positive normal assigned. After the shell element meshes are made I go to: Tools -> Query... -> Shell element normals And all of the elements are highlighted as having conflicting...

Hi, I have two objects that contact each other. When I have contact, I get an error that there are two improperly defined surfaces (there are only tow) and to check the normals. Normals have all been checked and verified to be in the same outward positive direction. Also, each object will...

Hi, I am running ABAQUS v 6.11.1 My model uses exclusively shell elements, to which I want to apply a uniform pressure distribution. When I do this and submit the job, I receive the error: "Error in job PAB1_31: SURFACE ASSEMBLY__PICKEDSURF181 INCLUDES EDGES. EXCEPT FOR SHELL EDGE LOADING...

Hi, I understand that the mass matrix can be output with the lines: *STEP *MATRIX GENERATE, MASS *END STEP In a linear perturbation analysis, but how can I view the diagonal lumped mass matrix of my dynamic explicit analysis? Is there anyway to view the diagonal values of the mass matrix [M]...

Edit: My elements are homogeneous shell

Hi, I finally got my Fung-type model working, but now the damping I need is not working. I receive and error message indicating damping can not be used with an anisotropic model. How else can I enforce a damping component to my model? I want to simulate fluid effects so I was using the alpha...

Hi, I am trying to get a generalized fung material model working. So far my input file has yielded the error along the lines of: the material needs more lines to completely be defined. Here is what I have in my code so far: ** **MATERIALS ** *parameter density= c= c1= c2= c3= c4 c5=...

I found out that there is no support for anisotropic hyperelasticity in CAE, but can be used by editing the inp file. Does anyone have a sample of a Fung Type material definition input I could use for a dummy? PJ

You will need to refine your mesh, or change the elements you are using first. You simply can not "turn off" the error. PJ

My Fortran user subroutine files calls on material props(1)...props(7), when I define the material in CAE as user-defined I select the number of material parameters to 7. However, there is no location to enter the constants. Where can I define these material constants? I am assuming it is...

Go to "tool" and add a Reference Point

Hi all, How can I access a Fung-type material model in CAE v6.8? Thanks, PJ

How can I upload a user subroutine in CAE? PJ

Hello, I just started ABAQUS last week so bear with. Im trying to get two (2D) beams to come into contact and continuously deform together under a distributed load. I can not get the beams to stop going through each other. When I define a master/slave surface along with ridged constraints...
