Dear colleagues
Hope you're fine.
I'm modeling a 2D-Axisymmetric model of a dental implant in the jawbone.
I need to know if the applied boundary conditions are reasonable?
I have only constrained the boundary of the cortical bone in the vertical and rotational (about the axis of rotation)...
Hello everyone
I'm trying to model a threaded connection by a 2D axisymmetric model.
I need to use anisotropic material properties for a part in this model.
Is it applicable to assign anisotropic material properties to a 2D axisymmetric model.
If yes, how this can be done?
Best,
Yunus.
Dear colleagues
Hope you're fine.
I'm trying to model a threaded connection with a 2D axisymmetric model.I need to make several models with slight changes and differences.
When submitting some models for analysis they get aborted due to
some nodes have Negative coordinate values error.
When I...
Dear colleagues
I wonder how I can call and use STATEVs of previous increment(s) in UMAT subroutine?
Thanks in advance.
PS: I know that in USDFLD subroutine you can use GETVRM utility routine to access STATEVs and any other material point variable but in UMAT this utility routine can't be called.
Hello dear colleagues
hope you're fine.
I wonder if there is a way to average a field output (eg. Von mises stress) in last 10 increments for each element using:
a. Abaqus subroutines
b. Abaqus python scripting
c. any other way
Thanks in advance,
Yunus.
PS: I'm using the USDFLD subroutine...
Hello everyone
Hope you are fine.
I have 2 questions about USDFLD:
1. In case I have 3 Materials (3 Field variables) and I am using USDFLD in the 4th step, by which Material the analysis gets done in 3 previous steps?
In another words, before USDFLD starts working, which material is used?
2...
Dear coleagues
Hope you're fine.
I have two cylinders. The outer surface of the smaller cylinder (lets call it Pin) is in contact to the inner surface of the larger one(lets call it Box).
The contact type is surface-to-surface and by a friction coeficient of 0.8 (tangentioal behavior>>penalty...
Dear colleagues
Hope you're great.
Using USDFLD subroutine, I want to choose material properties for the new increment based on the average of a variable (eg. S11) in last 3 increments.
Do you have any idea that how can I do so?
For example, how can I call the value of S11 in previous...
Dear colleagues
Hope you're fine
Using USDFLD subroutine,
how one can be sure which component of the desired variable is he/she using?
For example we know that 1,2,3...6 components of Stress would refer to S11,S22,S33,....S23 but what about other variables (eg. FLVEL
Current magnitude and...
Dear Colleagues
I'm trying to get results file (.fil) from Abaqus.
I have checked the below attached links but couldn't figure out how to use "*EL FILE " keyword to achieve this purpose.
I tried adding the following lines to the Job-1.inp file and import it to Abaqus as a model but get the...
Hello everyone
I'm trying to use USDFLD subroutine to solve a simple problem of a bending beam in which I want to change the material based on tension/compression status of the elements.
I want to assign MATERIAL 1 to elements under tension and MATERIAL 2 to the elements under compression.
I...
Hello everyone
I'm trying to run a 2D-axisymmetric simulation of a threaded pin in a drilled box, to see the effects of screw insertion torque and axial loading according to the example of Abaqus documentation "Axisymmetric analysis of a threaded connection" ...
Dear colleagues
Hope you're fine.
I'm trying to link Abaqus 2019, Visual Studio 2019 and intel parallel studio 2020 to use subroutines.
while running Abaqus verification the Abaqus/Standard with user subroutines ends up with an error:

Hello everyone
Hope you are fine.
It is conventional to simplify a 3D model to a 2D-axisymmetric equivalent model for the sake of simplicity.
the question here is if a 2D-axisymmetric model could be converted to a 3D equivalent model?
For example, you have done your 2D-axisymmetric simulation...
Hello everybody
Hope you're doing great.
I have defined two interactions for a contact pair. The second interaction is created after the first one gets inactivated.
The first interaction is a Frictionless contact and the other is a Rough contact.
I keep getting the below-mentioned error while I...
Hello dear Abaqus users
I have problem running my simple simulation using subroutines.
Although I specify my .for subroutine file in the job panel I keep getting this error while submitting the job:
Error in job Job-USDFLD_Simple: Unable to locate compiler! Please verify your PATH settings...
Hello everyone
In a simulation that elements' material properties (eg. Young's modules) change during the process (eg. bone healing process):
1. How can one visualize different material properties during or at the end of the process?
2. How could elements' properties be recorded in an output...
Hello everybody
Hope you’re doing great
Assume I have two material properties MATERIAL1 and MATERIAL2. I start my model with MATERIAL1 and calculate each element’s (von misses) stress and if any element’s stress exceeds N MPA I change its material to MATERIAL2 and continue till all the...
Hello everyone
How could I assign a different material to each element in an Abaqus model?
for example:
I have two materials and a model consisting of 10 elements, I want to start the solution with Material 1 and if each element's von mises stress exceeds 5 KPa, Abaqus changes that element's...
