ANSA官方自带脚本Pids2Mids.py(路径：..\BETA_CAE_Systems\ansa_v22.0.0\scripts\Properties)主要功能是：对材料进行重编号，使mat与prop拥有相同的标识。若某一材料被多个prop共用，则复 制该材料，确保实现prop-mat一一对应关系。源码如下：'''==================================================* HEADER==================================================Developed by:Irene MakropoulouDate:26/01/2011 BETA CAE Systems Kato Scholari, Thessaloniki, GR-57500, Epanomi, Greece Tel: +302392021420 , +302311993300 Fax: +302392021417 E-mail: ansa@beta-cae.com URL: http://www.beta-cae.com Copyright (c) 2011 BETA CAE Systems All rights reserved.=================================================* DISCLAIMER=================================================BETA CAE Systems assumes no responsibility or liability for any damages, errors, inaccuracies or data loss caused by installation or use of this software.=================================================* HISTORY=================================================Date: Updater: Modifications:-------------------------------------------------Date: Updater:Modifications:-------------------------------------------------''''''Name: Pids2MidsDescription: Renumbers materials so that they have the same id with the properties.
