Error: Combinations in time are missing

On calculating of the (cracked) deformation over time , the following message appears:

Solution

1. Go to the Loads configuration and click on .
2. Fill out the 2 columns t₀ and Combination for cracking
   1. t₀: time at which the load applies to the structure [days]. Example: 28 days is a typical value for the self weight.
      
   2. Combination for cracking: reference combination for the cracking in time evaluation. Recommended is to take ELS RC 1, as all other evaluation of cracking in Diamonds is based on ELS RC.

   

3. Click ‘OK’ to close the dialog.
4. Click on .
5. Generate all combinations automatically and click ‘OK’ to close the dialog.
   
6. Recalculate the model , run the reinforcement calculation , run the deformation over time .
