Please help me with this, I am doing my final year project but very new to ANSYS mechanical apdl. How can I combine two files into one file on ANSYS? I created two structures on the apdl, but I need to put them into one assembly to proceed the analysis. I need to combine the designs into one window. Is it possible? Thanks for helping me.

Resume the other, then read in the CDB to combine the two models. nThere is a numbering offset command, NUMOFF, that goes along with the CDWRITE command. This was you can offset the node/element/etc numbering of the CDB so that it does not conflict with the existing FEM in the DB. Please review the following help section, then maybe practice with two simple test models so that you can easily inspect the combined model.n12.1.

Resume another db file and then import the cdb file in it. You might need to use NUMOFF that goes along with the CDWRITE command to offset the element,node numbers. Please check the Ansys help for more details of the commandsnhttps://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v211/en/ans_cmd/Hlp_C_CmdTOC.htmlnThe another way is you can export both cdb file. In Workbench you can import them using two 'External model' and combine them in single analysis system. From the analysis you can write the APDL input file.nnFebruary 4, 2021 at 4:28 pmHuijuanSubscriberAlright, I will try this method and update if it's working. Thank you very much nFebruary 6, 2021 at 2:16 pmHuijuanSubscriber

Would you help me to take a look? I created two models and meshed them then use the CDWRITE command. nIs this the right way to set up the files to read on mechanical apdl? I used CDWRITE, ALL, , CDB, , Aligner, , blocked for the CDWRITE code. for both of my files, but when I imported on workbench, linked them together and open on APDL, it was empty. nHow should I command the NUMOFF? I couldn't see the link you shared, probably because I am holding on student's license.nnFebruary 8, 2021 at 2:24 pmRahul KumbharAnsys EmployeePlease check thisnHow to access ANSYS help linksnViewing 5 reply threads
