Hi.
I'm encountering a bug with both Plaxis v21 and v22. I'm using the python-api to create and analyse models. However the surface loading is not working as expected...
Upon inspection of the output view, it shows that load 4 is active (which is applied at level "b") - which it is not as shown in the above image. Console messages and the model explorer show that load 4 is not active.
Note, upon checking Y stresses it is applying the loads wrong. Which is different to the 2015 error reported here: communities.bentley.com/.../incorrect-visualization-of-multiple-points-loads-in-plaxis-2d-2015
Any ideas?
Many thanks,
'Matthew
PS, like i say, I'm using the python api to run various iterations (varying berm geometry) but some/most of the models do NOT have this bugged loading.
Hello Matthew,
I am seeing that Phase_15 did not finish the calculation, which means that ΣΜStage <1.00, the deactivated load from the previous phase might not yet be fully deactivated.
Please read this article about it: Deactivated loads are still visible in PLAXIS Output
I would check in Output for the table of loads that shows their magnitude under Project > Load information.
If you still have questions about it, please submit a new Case for support. Then, one of our support engineers can help you in detail: https://bentleysystems.service-now.com/csp
Hi Stefanos, thanks for your reply. That makes sense to some degree then - as the load is in the process of being ramped down. The reason the stage did not finish calculating is due to load advancement issues - which as I say is quite odd, as all that is changing is the geometry of the berm infront of the wall (slightly varying width / height). I found a smaller berm geometry managed to calculate, but a larger one was having numerical issues...
I've tried disabling arc length control, however a wall-top of berm node is exploding.
An "exploding" node (or "flying" node) usually is related to the strength assigned. Sometimes numerically, some small strength (cohesion, tensile strength) is required to prevent them from getting unrealistic deformations.
As this is project specific, if you want us to give it a look, please open a Case for support.
