Hi karachun
I studied nonlinear adaptive meshing. unfortunately all these methods are used in structural static analysis. is there a way to implement this method in transient analysis. in the other hand my analysis is coupled analysis and I use solid226 to do it ( not including special elements...
hello Karachun
thank you for your response, those links you sent, were included in handy informations. I am on it hopefully to simulate the process completely. used element is solid226
I am using ansys apdl ( not familiar with ansys workbench) meanwhile the analysis type for me is transient (...
Hello everyone
I am modeling FSW ( friction stir welding). I already simulate it using the tool that had no pin only including shoulder.
Lately I wanna simulate the process with tool including shoulder and pin which should penetrate 5.6mm but my simulation became divergent after penetration of...
hello guys
i have 3d model so that its surface located in ZX plane of coordinate system. if i wanna impart residual 2d tensor on the surface with inistate command, what components should i consider?
I mean if i should consider sigmaxx, sigmaxy, sigma yy or sigmaxx,simazx,sigmazz?
i dont know...
hello guys
i have model ,i meshed area by area. finally wanted to merge it but i encountered the errors
i attached the log file. it would be appreciated any suggestion or...
HELLO
the photos that sent to me it belongs to direct mesh generation of target that i modeled it but results are not good. the model that now i am working on it include of ball with finer mesh (indirect mesh generation). i attached photo of it..but it wasent converged. even i refine mesh of...
thank you L_K for the response
as i mentioned above i modeled movement ball on the plate by direct generation tar get element. but results are somehow unrealistic.
i want to model in other method and my problem as follows:
the simulation is 2 step: ball impressed to the plate, second step...
Hi guys
I am modeling movement of rigid ball under force on the plate.
the simulation is 2 step: ball impressed to the plate, second step: impressed ball moves along the plate and simultaneously it rolls. but in the end of second step ball full penetrate on the plate(so that some part of ball...
but i have question and i think maybe would be simple that i dont know its answer.
if in the same model i want to model cylinder or other object to move along the path( the same path that ball has gone) what do i do? i mean how deactivate ball in my model,,because i need plate ( with initial...
hello my friend.
my model was converged by changing keyoption(4)=2 for element contact174
results almost is realistic and unrealistic but i will work on it.
i wanna appreciate you and thanks alot for valuable points that you mentioned
good luck
cyrus
hello
thank you for your valuable points. i changed behavior of contact from standard to bond initial and i got reasonable results in load step 1..but now i
am doing every work for convergence in load step 2 but my solution wasent convergence.
if you encountered similar problem in ansys...
hello
i modeled it in touch without any gap but the result is nothing again.truly i am executing in static analysis..would it be a cause of problem?
maybe i should model in touch without gap and increase gradually force by subsequent load steps...but anyway thank you for your response
really i...
hello L_K
we have a plate and ball. the ball should be pressed to the surface of plate.
i modeled it and imparted displacement(300micron) to pilot node of ball and observed results ( like von miss and other stresses) and checked reaction force in pilot node that was almost 24000N.. then i want...
Hi guys
is there any sample for indentation of rigid body on deformable plate.
i modeled it by imparting displacement to rigid body.. but when i use force on it i cant drive realistic results..
it would be nice of you if guide me this problem with imparting of force
hello
I am using ansys mechanical apdl.I have plate and disc. i want to impart force on the disc and then to roll it.deformation on the plate is important for me. my question are:
1- can i model disc as rigid body? if yes how?
2- how can i impart force and then roll the disc?
i modeled...
hello L_k
thank you.
I am using ansys apdl...and the tree you mentioned i dont know where it is.
i am doing subsequent analysis and i have to model it in ansys/multiphysics apdl. but one of objects is not important in my analysis
primary analysis was done in the ansys/multiphysics apdl .thats...
