  Hello everyone,
  I am new to FE analysis and creating my first models.
  I tried to model a concrete pavement and see how it deforms under temperature. With a higher temperature on top and a lower on the bottom, the concrete should develop warping stresses and bend upwards. Unfortunatly my concrete slab bends downwards. Any ideas why that is?
  As engineering data i used standart concrete.
  Do I have to use any special APDL commands to simulate concrete with Ansys Workbench or is it possible without?

  nPlease explain how you created a temperature gradient in the model.nPlease show how the model is meshed.nPlease show how the model is supported.n
