HI Thank you 76185 , As you have said i found the related code lines in examples. What should i do now for solution mapping? I consider next steps as follows : remesh the deformed shape and introduce boundary conditions and loads once again write input file and add * map solution and step and...

Hi Thanks , I will try that although it apparently includes some deficiencies.there most be a command in abaqus to perform this directly. Regards

Hi Dear Friends I am trying to use * map solution option in abaqus. I use CAE. I have imported the deformed shape from odb but it is in orphan mesh form.Is it possible to extract a solid geometric part from it in cae? Thanks

Thank Spirit, But it is almost the same. What I mean is to devise a way in which the pressure exists in the pipe and the pipe tends to suck in everything placed near its opening rather than exerting the pressure on the model(object). this two are different as in the later the pressure boundary...

P.S. Of course I mean without any fluid flow in it.

Hi My friends How Can I introduce a suction pressure in my axisymmetric pipe ( I mean without exerting the pressure in an adjacent surface since I want the pressure be an inherent property of the pipe itself and not to be exerted on something else and the pipe play the role of a mere rigid body...

I want to simulate the suction of a cell into a pipette My model consists of a analytical rigid pipette and a spherical cell modeled axisymmetrically : Properties : Viscoelastic (SLS) Interaction : frictionless Hard contact 1- If I want to exert the instantaneous pressure I will face sever...

It seems that I have finally understood what my problem is.My load is instantaneous,therefore excessive distortion is inevitable.I have to substitute this with a ramp load.Increasing frequency also helps to prevent distortion as far as I have understood.Another interesting matter is mass...

Dear Xerf As much as I have understood, increasing the frequency will request the adaptive meshing procedure to occur more often and therefore distortion will be procrastinated. But in my case I think that distortion is inevitable since the loading is introduced to be instantaneous which means...

Dear Xerf Your idea initiated some doubt,I will check this. Thanks dear, Bests

Hi! Dear Xerf For the 1st point,I am of the opinion that your model should answer regardless of the mesh type you choose, yeah;using tri elements or a coarser mesh help but why shouldn't I be able to elicit answer with quad for example? So I guess that the fundamental problem lies somewhere...

Hi! Dear williwang The method which you mentioned(Mesh to mesh solution mapping )is,as far as I know,not a very time-friendly one,besides I am not familiar with that process.I have put it aside as the last card when all the other otions failed to answer.I am still experimenting ALE and will let...

Dear Xerf For the first remark The material model is considered to be viscoelastic at the time ,I may consider the effect of hyperelasticity later. And to the 2nd is absolutely yeah! Unless you're fully aware of what you are changing,which I at the time do not know. Thanks and regards

I will let you know the possible solution as soon as i have reached any answer,But till now the problem is still ambiguous and nobody seems to have an opinion toward this matter:D

Hi My friends In my model, which is suction of a gel to a pipette, the step visco fails to converge and yields the error of "too many attempts "at the beginning or middle of the procedure which is likely due to "excessive element distortion". Tricks like altering *CONTROLS will only delay the...
