For our NX Nastran Advanced Non-Linear Customers
ADINA R & D would like to keep NX Nastran Advanced Non-Linear (SOL 601/701) customers very satisfied and continuously served with valuable solution capabilities. Hence, please note:
The ADINA solver can be used with Simcenter 3D and Femap pre/post, so NX Nastran customers can seamlessly migrate from SOL 601/701 to ADINA without changing their workflow.
Many Sol 601/701 users have already decided to continue with ADINA usage
Many NX Nastran customers have already smoothly migrated from SOL 601/701 to ADINA. These customers are pleased with the smooth migration and the additional solution capabilities now available to them in the ADINA solver.
From SMART Engineering GmbH in Germany, committed to ADINA, received June 17, 2020:
“As German FEA specialist for Simcenter (Femap, Nastran, NX, FLOEFD) with more than 24 years of experience in sales and consulting, we have been using the ADINA technology as SOL 601/701 solver since the integration into NX Nastran. During this period we have successfully completed numerous customer projects in the fields of non-linear statics and dynamics and have come to appreciate ADINA as a reliable, robust and fast FEA solver. The large range of functions and the good handling in combination with the Femap preprocessor have also contributed to this. These reasons have left no doubt that SMART Engineering will continue to rely on ADINA technology even after the discontinuation of SOL 601/701. Most of our software customers, who have been benefiting from this technology for years, have also followed this example in the meantime.

Default solver settings for ADINA and SOL 601/701
Some default solver settings are different for ADINA and SOL 601/701. The major differences are:
- SOL 601/701 uses the Newmark implicit time integration method by default, whereas ADINA uses the Bathe implicit time integration method.
- SOL 601/701 uses incompatible modes by default, whereas ADINA does not.
The ADINA program philosophy is to use, by default, reliable and robust solution techniques. Please see:
When the ADINA solver is launched from Simcenter 3D and Femap pre/post, the SOL 601/701 default solver settings are used.
When the ADINA solver is launched from the ADINA User Interface (AUI), the ADINA default solver settings are used. However, the AUI option flag “-sol601” can be used to set the AUI to the SOL 601/701 default solver settings.
Hence, the difference in the default solver settings is only applicable when solving a SOL 601/701 model by launching the ADINA solver from the AUI. In this case, the “-sol601” option flag can be used to instruct ADINA to use the SOL 601/701 defaults.
The ADINA Handbook gives a complete list of the differences in default solver settings for ADINA and SOL 601/701.
