In the Abaqus system shown in the figure, three analysis steps are set up: step1, step2, and step3. In the step1 static analysis step, a pretension is applied to the top of six anchor cables. In the step2 static analysis step, net buoyancy is applied while the pretension remains unchanged, and...
For a general section beam element with eccentricity, if the output point is set at the centroid position z=-1, will the line load be loaded at the centroid position z=-1 or the beam element position z=0 on the diagram?
Why are the element stress values obtained using the PYTHON code different from the element stress value obtained by querying directly in the CAE interface?
The code is as follows:
odb = session.openOdb('odbname', readOnly=False)
ele =...
I would like to ask a question about internal forces in section: in ABAQUS, the output results of internal forces in section of beam elements (SF1,SF2,SF3,SM1,SM2,SM3) are obtained based on the local coordinate system. Are these 6 components based on the local coordinate system that was not...
Why is it not possible to output the connection force of a rigid connection of multiple separated lines using ABAQUS CTF? I wonder what the problem is besides? Even though the output CTF is set in the field output, I can't find the CTF in the ODB file, or all the CTFs and CTMs are 0. What is the...
In ABAQUS, is the SF and SM of the nodes output from the beam model based on the post-deformation beam local coordinate system or the pre-deformation beam local coordinate system. If it is a post-deformation beam local coordinate system, does this mean that the orientation of this coordinate...
1. In ABAQUS, for a three-dimensional cantilevered cylinder structure, there is only a force in the Y direction at the top of the free end, so why is there a branch reaction force in the X and Z directions at the solid end (with all six degrees of freedom constrained)?
2. The support reaction...
As shown in the figure below, a cantilever beam is subjected to a vertical downward force at the apex of the free end. It is logical that only fy,mx has significance, and fy,fz,my,mz are all 0. But why do fy,fz,my,mz still have values?Why is fy uneven -1e7?
Can tie (but not constraining rotational degrees of freedom) be equivalent to MPC PIN?
What is the difference between these two types of constraints as shown below?The calculation results of them.have little difference.
1. In ABAQUS, when tieing a face and a node set, if the slave face is composed of a node set, is it only at the node's contact position with the face that there will be constraints? Will slave nodes and slave nodes bind to each other? Will the part of the slave node that is not in contact with...
When using beam units in ABAQUS, you have to define the shear center. How to find this shear center for a very complex section? Is it possible to leave it undefined? (I've seen a lot of software in the forum, such as ShapeBuilder, where I imported a complex circular section and ended up with a...
Can AQUA inside ABAQUS calculate random waves? For example, given the peak period and effective wave height, do I have to write my own code to calculate it?
Experts, I would like to ask is there a way to solve the problem according to the time step in ABAQUS? That is, load once and solve once, but do not end the solution, the second time continue to load on the results of the first operation, continue to solve, and repeat this process. Can this be...
Dear experts, I would like to ask how to constrain the contact between the truss unit and the surface of the cylinder shell in ABAQUS in a reasonable way? I tried to use a mpc pin connection between the endpoints of the truss unit and a bit of the shell unit, but this results in a large stress...
