$$$$ TRIE NOTICE BP208322 12/12/20 21:15:29 7632 DATE 12/12/20 Operateur TRIE -------------- ------------------------------------------------------------ Syntax 1: sort elements according to level set functions ------------------------------------------------------------ MCHAM1 | | = TRIE MO1 CHP1 CHP2 | | ; | | | 'SAUT' | | REL1 | | 'DESE' | Description : ____________ The TRIE operator select element from xfem model and compute a MCHAML object of enrichment. When 'SAUT' is present, the displacement approximation is only H-enriched, the crack tip has to be on an element edge. When 'DESE' is present, old crack tip's enrichments are progressively droppen : the one associated with crack tip at time n-1 is forgotten, the one of time n is imposed to 0 (with REL1) and the present one (time n+1) is added. Comments : _________ MO1 (I/O) : MMODEL object with xfem element to sort/ MMODEL object with sorted xfem element CHP1,CHP2 (I) : the two CHPOINT objects representing level sets MCHAM1 (O) : MCHAML object of enrichment. 'SAUT' : optional keyword to avoid crack tip enrichment 'DESE' : optional keyword to enable step-by-step change of crack tip enrichment ------------------------------------------------------------ Syntax 2: sort elements according to a prescribed enrichment ------------------------------------------------------------ TRIE MO1 MCHAM1; Description : ____________ The TRIE operator sort the elements of xfem model from the given MCHAML object of enrichment (built with syntax 1 of TRIE). It enables to re-build the model at the configuration associated with MCHAM1 Comments : _________ MO1 (I/O) : MMODEL object with xfem element to sort/ MMODEL object with sorted xfem element MCHAM1 (I) : MCHAML object of enrichment.
