Hello everyone.

I am solving a tutorial where the idea is to simulate a reinforced concrete beam. I followed each step of the tutorial, but at the end I am receiving the next message

"An unknown error occurred during solution. Check the solver output on the solution Information object for possible causes"

I click on the solution information folder and select all the text, see the attached file. I am also attaching my model. 

Thanks for any help with this issue

You can look in the solution information and if you search (ctrl+f) for error, and you will see that there 5. Most of the are related to the MISO material data.

1.*** ERROR ***                           CP =       3.884   TIME= 22:00:05

 For material 1 at temperature 0, the initial slope of the stress-strain
 curve based on the TB,MISO table ( 30910 ) is greater than EX (29600). 

 

You need to adjust the EX to 30910 if that is the correct E mod. Otherwise you need to fix the stress strain curve so it gives 29600.

 

2.  *** ERROR ***                           CP =       3.884   TIME= 22:00:05

 TB,MISO table for material 1 at temperature 0 has a tangent slope of   
 its stress-strain curve ( 30890 ) greater than EX ( 29600 ). 

 

Again it is the easiest to set EX to 30910, and this error would go away.

 

3. *** ERROR ***                           CP =       3.884   TIME= 22:00:05

 TB,MISO table for material 1 at temperature 0 has a tangent slope of   
 its stress-strain curve ( 30940 ) greater than EX ( 29600 ). 

 

So you need to sort out the stress strain curve it cannot have a slope greater than the initial slope which is 30910.

 

Also the steel plate I would use a bonded contact since it slides now as it is, or frictional if this is not bonded (no separation is similar , that is contact surfaces can not go through or separate, but in  this case it allows movement along the contact surface, while bonded is like glued so no relative movement/sliding between surfaces).

If you just want o run and see check the model, just set EX to 30940, and bonded contact. Not saying though that this is correct. Correct course of "action" is to put the correct stress strain curve
