In my case I need to define my material properties by APDL-Script. To make sure, that the APDL-Script really works correctly, I made a reference case where I use the material properties directly from Enginerring data. In the reference case I use the defaut material &#8220;structural steel&#8221;, and in APDL-case I implement the structural steel in APDL-Script, which makes the enginerring data ignored. So the reference case and my case should now have the same properties. I also use the same boundary conditons for the example plate, with one side fixed and another side a force excitation.&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681827433-mceclip6.png\"><\/p>\n<p><strong>(Case with APDL-script to define material properties)<\/strong><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681826841-mceclip0.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681826941-mceclip1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681827187-mceclip4.png\"><\/p>\n<p><strong>(Case with engineering data to define material properties)<\/strong><\/p>\n<p><strong><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681827003-mceclip2.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681827032-mceclip3.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/04\/18-04-2023-1681827201-mceclip5.png\"><\/strong><\/p>\n<p>Since I have the same materials and the same BCs, I should get the same results, but the deformation response looks totally different, can someone help me solving this problem?
