Warning - very small embedded beam elements generated

Question

Hello! 
 I am running a model with many embedded beams and plates on top (piled raft) and when meshing I am recieving this warning, "very small embedded beam elements generated". Is it something that effect the results? 
 How can I solve it? Tried meshing with medium and finer local mesh for the beams. I do not want to make vey fine mesh because then the model will take forever to run (have several long consolidation stages). 
 Regards,

Dear Khaled, 
 The error you receive states that you have small size embedded beam elements generated which may cause problems in calculations. However it is not a major error, but rather something to attract your attention as if you can prevent it, it can possibly avoid calculation issues. 
 A first step would be to check which embedded beams are causing the warning. You can use the tabulate command to identify the small objects' size (here length) in Mesh and Structures mode: 
 tabulate Lines "Length" "Length<0.1" 
 This will search which lines have a length smaller than 0.1 length units. You can find more information on the tabulate command in our Command reference and our article here: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45942/obtaining-tabulated-data-from-plaxis-input 
 If you find that the findings are as expected and required to be modelled as such, I would suggest creating a box of surfaces or a volume to surround these embedded beams and apply local coarseness factor rather than changing the global coarseness setting to Fine, as it would affect the whole model (which you correctly pointed as not needed and time-consuming).
