5．REVISED FUNCTIONs in ADSTEFAN Ver.2017

5-1. General

5-1-1. Revision of license management policy

・Manages executing job number instead of CPUs number, for utilizing parallel computation and Message Pass

Interface(MPI) more than usual.

(*) Upper bound of partitioning number about region in MPI is same as license number.

Fig. Example of License Management

5-2. Mesh

5-2-1. Algorithm for automatic mesh generation

・Revises the calculation method for opened ratio and occupied ratio in casting mesh for blended element method.

This enables temperature analysis for a rough mesh of blended elements*4

with high accuracy in a short

period of time.

・By applying the logic for mesh generation in blended element, normal element can be also handled.

properties is used.

If temperature dependency is defined in the

table of material properties, material

properties in initial temperature of each

material is introduced and used.

5-3-1-2 Creating Initial Temperature

・In mold material, initial temperature can be arbitrary generated.
