Eric usually do you consider the material non-linear beahaviour or you adopt the linear curve? it's really hard find plastic curve and information for different materials.
Erik do you have a database where it possible have download material proprieties for Ansys. Matweb is not a free database and besides there isn?t any plastic behaviour material descriction.
thanks again
Dear Erik you have right!!
The problem is that i was seeing 2d surfaces without setting it right.
Now i designed the 2d skecth directly on design model without importing it from a cad software (conversion errors!!)
Below i report you my updated simulation but it's not working for convergence...
Dear L_k I decreased the load step (the displacement of 5 mm was decreased in 2 load step). I increased the substep to 500 but there's again penetration of spring and so any deformation. The mesh also was increased but i can't understand what is wrong!!
Dear Erik,
thanks for the reply.
The model is 2d (you see 3d because i active 3d ansys representation).
yes basically it's a rigid body movent. I set a friction coefficient of 0,1. Anyway geometrically it should there be a spring deformation but it doesn't happen.
Why?
Dear friends,
I'm dealing with a spring sheet inserction on a tube.
I'm conducting a static structral analysis because i would understand the max stress on the spring element.
The simulation is a 2D sim. to let reduce the computing time.
The friction contact was regularly detected (see image...
Dear L_K,
thanks for your help, you are a nice guy!!.
I have 2 hard disk (C and E unit)
The total page file size is 80 GB + 90 GB (see the images).
the RAM SYSTEM MEMORY IS 20 gb.
The program is intalled on C unit although the directory file is on E unit.
Hi,
i'm simulating a huge model-
During the simulation appears this error:
"There is not enough memory for the Distributed Sparse Matrix Solver to proceed using the out-of-core memory model. The total memory required by all processes = 165458 MB. The total physical memory that is available on...
Dear L_K i made the thermal analisys through the steady state thermal package (Ansys). Due to the fact that it's not possible calculate the total heat power dissipated from an amount of surfaces (named selection) could you indicate a way to post process the txt results (node numbers, x y z...
Dear L_k,
attached I post an example of the contact problem that i found makinf "repair overlapping contact" (after the program automatic repairing the contact is suppressed).
In the attached image I have insulated only 1 failed contact.
Consider that i have yet made the following corrective...
ok,i splitted the body as you suggested. The problem now are the bodies that share more contacts. In fact if a body is linked to more bodies it has more contacts. Fluent is able to deal with one body- more body contacts?
What do you suggest? Use named selection to by-pass this problem?
thanks...
Dear L_K,
so i have to split a single surface in many surfaces to build one contact to contact surface?
The surfaces created in spaceclaim have to be treated through the named selections?
Thanks!
Hi,
i'm making a CFD (Fluent simulation) of a battery with a lot of compontents. Around the battery there's an enclosure. This air enclousure is around but also inside the battery (air channels).
There are a lot of contacts beetween the components and after the meshing operations i have...
