3. C modeling#
3.1. But#
The aim of this test is to validate the use of 3D modeling on support mesh HEXA8 in CALC_EUROPLEXUS. It is already possible in EPX not to read an initial stress state on the corresponding elements. We will therefore also use and validate this feature which was immediately activated in CALC_EUROPLEXUS.
3.2. Description#
This test is the equivalent of test case EPX bm_cub8_ini_med_cont.
It is a cube formed by a single element. The lower face is embedded and a loading (imposed displacement) is applied to the upper face. This calculation is done with the operator STAT_NON_LINE in order to produce an initial state for the calculation EPX.
We then launch CALC_EUROPLEXUS with this initial state (movements + constraints) and without additional loading than those that allowed us to obtain the initial state. It is then expected that EPX will obtain a balanced initial state. We go through a hundred steps of time. We get the result and we check that nothing has changed compared to the initial state.
3.3. Principle of validation#
Comparison with the initial state.
