In this paper we use a variational approach in order to prove the geodesic connectedness of some Gödel type space-times; moreover direct methods allow to prove the geodesic connectedness of the Gödel Universe. At last a result of geodesic completeness is given.

✦ Synopsis
Given two points of a generalized Robertson-Walker space-time, the existence, multiplicity and causal character of geodesics connecting them is characterized. Conjugate points of such geodesics are related to conjugate points of geodesics on the fiber, and Morse-type relations are obtained. Applications to bidimensional space-times and to GRW space-times satisfying the timelike convergence condition are also found.

## Abstract The material point method (MPM) is a computationally effective particle method with mathematical roots in both particle‐in‐cell and finite element‐type methods. The method has proven to be extremely useful in solving solid mechanics problems involving large deformations and/or fragmenta
