In Abaqus/Explicit the element stable time increment can be controlled by the continuum shell element thickness, particularly for thin shell applications. This may increase significantly the number of increments taken to complete the analysis when compared to the same problem modeled with conventional sh...

***WARNING: THE ANALYSIS MAY NEED A LARGE NUMBER OF INCREMENTS (MORE THAN 300000), AND IT MAY BE AFFECTED BY ROUND-OFF ERRORS. RUNNING THE DOUBLE PRECISION EXECUTABLE IS RECOMMENDED.(增量步数超过 30000,建议使用双精度来计算)【常见问题10-6】 ODB 文件中的计算结果是否可以是双精度的? 42 第11...
Abaqus automatically chooses appropriate load increments and convergence tolerances and continually adjusts them during the analysis to ensure that an accurate solution is obtained efficiently. 1.1 The Abaqus products Abaqus consists of three main analysis products—Abaqus/Standard, Abaqus/Explicit,...
In the simplest case yes, but if you have very small time step you have a lot number of increments and then you might have wrong results due to numerical errors. The best is to use time step which Abaqus calculate at the beginning of the analysis, it depends on the mesh and material ...
In difficult cases, however, the solution procedure may not converge with the default controls or may use an excessive number of increments and iterations. After it has been established that such problems are not due to modeling errors, it may be useful to change certain control parameters. ...
Last increment of step(分析步的末尾增量步):此为默认选项,在该分析步的最后一个增量步结束后写入误差指示变量。ABAQUS/CAE根据最后一个增量步的误差指示变量对模型进行网格重划分。All increments of step(分析步中的所有增量步):在该分析步的每个增量步结束后都写入误差指示变量。若分析不收敛,读者可以使用最近...
