Hello, 

The difference between *ELEMENT_SOLID and *ELEMENT_SOLID with ten nodes format in LS-DYNA relates to the number of nodes and the element formulation used. The standard *ELEMENT_SOLID typically refers to elements with 4 to 8 nodes, which are used for various analyses in LS-DYNA. *ELEMENT_SOLID in a ten nodes format, such as the *ELEMENT_SOLID_T4TOT10, refers to a tetrahedral element that is converted from a 4-node to a 10-node element to enhance the element's performance and accuracy. 

Thank you,
AlexÂ
