Hello.

I used Mat 69 for a 2D plain strain problem. With a coarser mesh everything is ok but when I used I finer mesh (x8 the number of elements) I have a problem: 

ZERO OR NEGATIVE VOLUME FOR 2D-ELEMENT

Could you please tell me how to solve this problem.

Thanks

    Hi,

    Ensure element types are QUAD 4N (2D>Element Types option and update elements) and property is P14 SOLID for the elements. 

    Please update these and try running. If issue persist please share the model file.

    Hi.

    I increased the STFAC and it works. 

    I have the other question: what are the difference between ISOLID 14 and 17 in P14 SOLID? I have two differential deformation with them!

    Hi Pohan,

    These are different solid formulations. And i think this is due to the Isolid=17 hasn't the free shear-locking fonctionality like Isolid=14 which can result in different deformation.

    Hello @George P Johnson,

    I am trying to do so and i am still getting the error id. I am doing axisymmetric analysis for cylindrical part. 

    I attached the model below as I tried everything and cannot figure it out!!

    thanks 

    ERROR ID :          228
    ** ERROR ZERO OR NEGATIVE 2D SOLID VOLUME
    DESCRIPTION :
       ZERO OR NEGATIVE VOLUME FOR 2D ELEMENT ID=1

                  1 ERROR(S)

    Hi

    I think you should use ISOLID = 17 and Ismstr =2 for the Properties!

    HI,

     

    FInd the element with ID= 1 and check what is wrong with the element.
