Hello to all,

 I`m carring out a simulation with abaqus of an underground storage tank. I modelled the tank using shell elements (conventional) and for the soil I used solid element. I want the stress on the top of the tank caused by the efect of the soil that is on the top.

The applied load is Gravity in the y-direction (-10 m/s2) to the whole model and I`m using abaqus/standard. I defined the contact between the tank and the soil.

The problem is that the job end saying "too many attemps for this increment". I used different increments but all of them with the same result.

What can I do or what am I missing ?

Thanks to all!

Ezequiel

Hello ! I'm a beginner in Abaqus and for that I've tried to follow this tutorialhttp://fliiby.com/file/831535/i3rkmyhurs.html .

I was all ok until I tried to make the mesh (chapter 3.7.2 in tutorial). It said that they are parts of the assemby that are too complex to be meshed with those mesh settings.

The problematic zone is this:

Good Time to Everybody, I am working on Thermoplasticity, especially thermoviscoplasticity, will be comparing the results of some basic examples problem worked be Simo and Miehe, modelled in Abaqus with the results of a locally developed code. I am new comer in this excellent forum and I am happy to see myself among a nice community of Mechanicians. I regard all those who are conneted in this form and those who helped in connecting this chain of  Mechanics.
