SubscriberHello! I need help to get some steps to solve a problem during a restart. I'm trying to replicate the example of an earthquake analysis of a dam provided here: https://lsdyna.ansys.com/dams/
I organized the example files in separate directories and followed these steps (as described in the example README file):
1. Run dam-static.k 2. Run dam-auxiliary.k 3. Copy stat.d3dump01 from the static run (stat.d3full01 for MPP), and aux.gmbin from the dynamic run, into a separate directory for transient analysis. 4. Run dam-transient.k
I'm running on a small Linux machine, with ANSYS 2023 R2, and these are the commands I used:cd 01static
lsdyna -dis -np 8 i=dam-static.k jobid=stat
cd ..
cp 00motion/* 02aux/. ## 00motion contains the ground motion files
cp 00motion/* 03trans/.
cd 02aux/
lsdyna -dis -np 8 i=dam-auxiliary.k jobid=aux
cd ../03trans
cp ../01static/stat.d3dump* .
cp ../02aux/aux.gmbin .
lsdyna -dis -np 8 i=dam-transient.k r=stat.d3dump01 gminp=aux.gmbin jobid=trnThe error I get is as follows:
*** Error 10871 (KEY+871) For small deck restart, need to add *CHANGE_CURVE_DEFINITION for curve id 1 in the restart input file E r r o r t e r m i n a t i o n
I could not figure out or find information on how to modify the files to include the *CHANGE_CURVE_DEFINITION keyword and what syntax to use.
Any steps to help solve the issue are welcome.
Thanks.--Roque Lopez

Ansys EmployeeI believe you are using MPP, so please use "n=stat.d3full01" as indicated in the comments in the input files

SubscriberThanks, Ushnish!
I confirm that the static and auxiliary analyses run fine. No errors.
I tried with stat.d3full01, too. The error is different:*** Error 70008 (OTH+8)
restart file does not exist
./stat.d3full01.0000
E r r o r t e r m i n a t i o nThe 'stat.d3full01.0000' file does not exist.

SubscriberHello Roque,
The problems, as Dr. Basu has pointed out, are occurring due to the use of MPP. Change the last terminal command from
lsdyna -dis -np 8 i=dam-transient.k r=stat.d3dump01 gminp=aux.gmbin jobid=trn
tolsdyna -dis -np 8 i=dam-transient.k n=stat.d3full01 gminp=aux.gmbin jobid=trn
and I can confirm that it will work like a charm. The parameter
n
takes the restart input for MPP instead of the traditionalr
used for SMP.- Tonmoy.

SubscriberAh! Thanks again Dr. Ushnish Basu and Tonmoy!
I realize I missed the parametern
in the command example. I tried it and it's working now.
Thanks again for the speedy help!
