Hello FEA way, I kind of figure out why. My set is a node, so previously when I select stress/strain terms in history output, it doesn't have anything since stress/strain is element-based value. But when I select displacement terms in history output, it indeed writes to the input file! Thanks...

Hello FEA way, I selected them from the list. I just checked the values I want from the list and hit OK.

Hello, I used abaqus 6.13 GUI to request a history output2. And then when I write the inp file, the history output doesn't have anything I selected. Also, of course, when I run the job, the result doesn't have the history output2 as well. A screenshot is attached. H-Output-1 is the default, and...

Thanks Mustaines, it's a good suggestion!

Thanks FEA way! Yeah, I saw that. I will always use traction instead of pressure then since the traction will let me choose which area I want.

Hello FEA way, Thanks, as for the load-mechanical-surface traction, I indeed could choose traction is defined whether per unit deformed area/undeformed area. What about I just using the load-mechanical-pressure for the normal stress?? In editing the pressure dialogue, it doesn't specify whether...

Hello, When we apply the load-pressure in abaqus. If we select pressure, I wonder this pressure is the force divided by the undeformed area or the deformed area. In the large-displacement analysis, after the deformation, the area has changed. SO will my applied pressure be changed as well or...

The stress in the global coordinate is denoted as solid.sz, solid.sx and etc. I defined a coordinate system (sys2) in comsol. How to transform the stress in the global coordinate in the sys2? I cannot use sys2 in the solid mechanics and choose sys2 in the linear elastic material because my...

Hello, I want to know how to probe the value in the 1D plot in comsol. As for the 3D/2D plot, I can just click evaluation 3D anywhere in the figure and it will return me a value at that location (shown in the figure). How could I probe value in the 1D plot anywhere by clicking the location in...

Hello FEA way, When I define my material model that is Young's modulus is a function of the maximum stress. The result says it's not converging. However, it converges if I set a constant Young's modulus. Do you have ideas where I should change in order for it to converge? It doesn't work if...

Thanks FEA way, it makes more sense now!!

Hello FEA way, In the stress-dependent-elasticity, the material model given is where Young's modulus is a function of the pressure. As for the map solid.pm to p, why it is not just test(p)*solid.pm (weighting function times force)? I don't know why it needs to be test(p)*(p-solid.pm)? To put it...

Yes, I have checked that it. They gave the expression test(p)*(p-solid.pm). I am not quite sure what the expression means. Thanks.

Thanks, FEA way! Do you have experience in modelling stress dependent elasticity in comsol? My Young's modulus changes with stress. I defined a function for Young's modulus versus stress. I tried to use weak contribution and auxiliary dependent variable to solve the problem with the circular...

Hello, I am doing the same analysis in both abaqus and comsol, but they give me different result. So I want to know whether the single mesh size is same in two softwares. For example, I have total 35000 elements, how to check the length of the single element? Thanks.

Hello FEA way, Thanks a lot! It works~ Wenjing

Thanks FEA way, it works for z component! But what about I want to see the radial stress, sigma_rr? I tried to use solid.sx*sys2.T11 But the result I got is incorrect. Do you have any ideas where I did wrong? Thanks a lot.

Hello FEA way, It is also not correct. When I update solution, the original solid.sz solution changes. However, this stress tensor shouldn't change since it's correspond to the global coordinate stress tensor. That being said, I still think that the comsol treated my stiffness matrix I input is...

Hello, I want to visualize the stress tensor in the cylindrical coordinate. Currently, I have the output from a 3D solid mechanical model. The expression I choose is solid.sx, solid.sy, solid.sz and etc. However, these are all plotted in the global coordinate. I want to visualize the result in...

It's a very basic problem in order to know how the stress distribute around the hole. After the analysis, in the visualization, I created a cylindrical coordinate system in order to visualize the stress sigma_rr, sigma_tt. In principal, the sigma_rr around the hole need to be zero because it’s...
