I fixed all the problems. but now I have a problem with cam-clay when I use porous elastic I get this error. The sum of initial pressure and elastic tensile strength for the porous elastic material in element 774 instance soil-1 must be positive.

can anyone help me to fix it?

did you check?

and this paper is my referencehttps://files.engineering.com/getfile.aspx?folder=037828da-dbd0-4abb-b381-767da19582e0&file=1.pdf

I can't understand. my model is 3 layer soil with a piled raft foundation. one of my layers is soft clay and I define it by cam-clay and another one with mohr_cloumb .know I deleted all the plasticity properties my model was analyzed then I try all layers with mohr-cloumb but I get this error...

I defined geostatic stress in model but it doesn't fix

hello I'm working on foundation consolidation in Abaqus and I define my clay properties with cam-clay plasticity I get this error in analyzing The sum of initial pressure and elastic tensile strength for the porous elastic material in element 2161 instance soil-1 must be positive.

hello I cant fix this problem after a wile time I want to define ballast properties in abaqus with durcker-Prager hyperbolic shear criterion . I had internal angle of friction and dilation but I cant Understand correctly how can i define hardening .as I mentioned in previous post i have the...

I get this warning in my model how can fix it "There is zero VOL. FLUX everywhere in the model based on the default criterion. please check the value of the average VOL. FLUX during the current iteration to verify that the VOL. FLUX is small enough to be treated as zero. if not, please use the...

in exponent form need a and b.what is this ?

I'm sorry I cant understand this. Can I only use Triaxil test result to define? and Due to the result I mentioned in previous post What numbers should I enter in the form below?

now how can i define ballast property in abaqus look like article. I use hyperbolic drucker-prager and input Internal Angle of Friction and Angle of Dilation but my analyses is aborted with an error that say *drucker prager requires the use of *drucker prager hardening. how can fix it. in...

I need Drucker-Prager hardening how i can define it from result of Triaxial test

I want to model a rail way with geocell in abaqus look like the attach article . in article witch has stated to use the another experimental article that article is also attached to. how I can Defining Drucker-Prager hardening form that article...

I fixed my problem. i must to be use durcker prager for subgrade and baallast but i use mohr coulomb.

I think the problem from step 1 and gravity load because remove step2 and anlyze model then again i have that deformation.

Yes all fixed all the errors. The settlement is very diffrent to article.

density is kg/m3 and E is Pa why you say I use si(mm)?
