Hi, After generation of an error the Abaqus closed Automatically and I cant reopen my saved file giving the error: "rfm_StringManagerFile::String-String is not available" Is there anyway to revive my file? thank you so much Dariush

Hi,I want to model a pressurised container using Shell elements for the wall and Hydrostatic fluid elements for the fluid inside.I think i should modify the input file to generate fluid elements.right?but the problem is that the wall consists of several parts.I have no idea how to start the...

HI I wanted to know where to look for FLD of ASTM S234?Is there any literature source that would offer such data? Thank you so much Dariush

Hi I have asked this question once and i got good answers on that.so just check the archives you ll find the answer

hi what kind of damage nitiation have you used?most of methods are available in EXPLICIT solver.what is the problem you are solving?Is it not possible to solve the problem using Explicit solver? Dariush

Hi have you defined any failure initiation criteria?or is that an error that you get during solution? if it is an error that you get during analysis you should review your model again.it could be from material model,time period or contact.If you could n't find the problem i would suggest to...

Dear yoman I paste the complete question again here.Thank you so much for your attention. For defining A Ducatile Damage initiationas input data it requires Equivalent fracture strain at damage initiation and Stress triaxiality,which is a devision of Pressure stress and misses equivalant...

Dear Xerf i thought you would have the answer as you had last time so i asked the question here either. I m trying to read the COORD data from an specifies instance nodes.But i get an following error: this is what i wrote: myOdb = visualization.openOdb(path='initial.odb',readOnly=FALSE)...

Hi I m trying to read the COORD data from an specifies instance nodes.But i get an following error: this is what i wrote: myOdb = visualization.openOdb(path='initial.odb',readOnly=FALSE) firstStep = myOdb.steps['forming'] coords0=frame0.fieldOutputs['COORD'] coordxValue=coords0.values...

Dear Yoman Here 's my solution. First i found two points on eachside of the surface using the equation of the line passing through two nodes.(I wrote the equation base on an arbitary parameter 't')Then by passing a wire polyline the intersection vertex were created.Now it is possible to create a...

Hi I think i found the answer myself.I can explain it if any body needs to know! Dariush

Hi i want to know,how to define Pressure stress and misses equivalant stress?What kind of material tests should i do in order to define them? Dariush

Dear Greglocock I actualy found the solution to my question.So I dont need to go through maths behind the intersection.thank you for your comment anyway.and i m ready to explain the way to do such an intersection in ABAQUS if any one is willing to hear. Dariush

Hi Well I have the equation of a line passing through two nodes and also have a free surface model which i have imported by .model format from a CAD software(CATIA).I want to know at what coordinate this line intersecs the surface.Does ABAQUS CAD module has the ability to do that?if not is it...

Hi does anybody has Experience in defining A Ducatile Damage initiation?Well as input data it requires Equivalent fracture strain at damage initiation and Stress triaxiality,which is a devision of Pressure stress and misses equivalant stress.I was wondering if anyone could explain how to obtain...

Hi corus thank you for your comment But The problem is that the Abaqus has no feature for intersection of line-surface in fact the cad module of ABAQUS is so weak do perform this intersection!Am i not right? Dariush

thanks for the comment but i have already done that and no body came up with an answer

Hi here is the problem: I 'm developing an script(python).In part of that script,I should generate several lines by connecting node of current step of a forming process and previous step and intersect it with an arbitrary surface which is imported from a CAD software.The intersection points of...

thank you Xerf,too short but very helpful

Hi This question might be absurd to some of you guys,i know but i wanted to know in which cases a python script should be written and when a Fortran subroutine?what are the applications of a Fortran subroutine and what is the difference? thank you so much
