Thank you for the answer! Querying this number in the output database didn't give any hits for all instances (Tools -> Query -> Nodes). Is it possible to list/check/look the internally created nodes sets?

Hello, I have encountered a very odd error in my analysis. I got an error saying "***ERROR: Excessive rotation of node number 154156" while the listed node doesn't even exist in the model. I opened the .inp file and searched for "154156" which gave me no matches. I'm using the "initial state"...

It turns out this case can be described according to a certain saying in computer science: "It's not a bug, it's a feature." I got the answer to my question in the DS forum so I'm forwarding it here. One of the users said he remembers how it was implemented -- this feature was developed many...

Well, it turns out it doesn't work in Abaqus 2021. I created a new mesh and Abaqus gives me the same error as mentioned in my first post if I want to conduct the calculations with parts and instances ("***ERROR: Unknown global id: 23121"). However the node listed as unknown is now not the first...

I'm in the process. ;) The problem is that after this spike in the energy occurs the simulation starts to consume very big amounts of RAM and it just stops after some time (I didn't checked how much exactly but for sure more than 30 GB, while at the beginning it says it will use about 200 MB)...

Hello "FEA way"! Thank you for the interest! Yes, I have used the 'fluid cavity' functionality. I wanted to use this more sophisticated approach, as now I'm interested in the behavior of the structure with specific shape of the exhaust vent (and possibly some obstacles to the flow which could...

Hello everyone! I'm performing an SPH analysis of the airbag impact. It's equipped with an exhaust vent. The simulation goes well until some point in time when some rapid increase in kinetic energy of the fluid can be observed (it is unjustified and maybe it's a kind of an artifact or the...

I am using version 2019. If this is true, I hope I could get the access to the newer one.

Hello FEA way! Thank you for the reply. I followed your advice and queried the nodes of the instance, for which I want to use the reference mesh, in the odb file generated after the Data Check analysis of my model. They are labeled in such a way: INSTANCEOFINTEREST-1.11299, where the nodes...

I'm trying to define a reference mesh for my explicit analysis, but I want to define my model in terms of Parts and Instances in Abaqus CAE and then write the "*Initial conditions, Type=NODE REF COORDINATE, Input=xxx.inp" line in the inp file. The problem is that Abaqus will not let me to do...

Great! In the meantime I've also found that it can be exported with (Report -> Free Body Cut). As I wrote earlier -- it's not what I was exactly looking for, but it's still very helpful. Many thanks for your help.

Thank you 'FEA way' for your advice, it was really helpful. I read the documentation about this tool and it is very close to what I need. The problem is I cannot generate a history output from this tool. I tried to find a way of exporting it's values from field output type to history output...

I want to conduct a simple tensile analysis of a rectangular sample and get the corresponding force-strain curve. I know that I can measure the reaction force at nodes which belong to the displacement boundary condition. However I want to get also the force values measured somewhere in the...

Specifying a Reference Point of the fluid cavity in the Assembly module instead of the Part module seems to be a solution for the issue. Employing such approach results in no nodes with missing coordinates.

It's Abaqus 2019 and, indeed, they wrote it in 2020 version of the documentation. Suppose it's true also for 2019. There's still a question why it imports this point and marks it as a warning instead of just omitting it.

Thank you FEA way for you reply. Regarding your first bullet: The limitations you're talking about are described only in documentation for Standard/Explicit and Standard/Standard imports. There is nothing about that in Explicit/Explicit case. Did they missed it there? As to the second bullet...

I'm encountering some warnings while executing the import analysis and wondering if it's possible to get rid of them. The first Explicit analysis is the case where some airbag is filled with gas to some specific pressure value. The modelling approach is to use the fluid cavity. In order to...

I have a question about the theory standing behind the application of enforced motion in ANSYS. It can be found in Mechanical APDL Theory Reference (14.18 -- Enforced Motion in Structural Analysis). I am interested in the first two of them: 14.18.1 -- Full Full Method for Transient and...

Hello. I thought that spline is just spline, not B-spline or NURBS. Thanks for your response.

It isn't what I was expecting, but thanks for the response. ;)
