Dear all,
My name is Willem Roose from Belgium and I am a student at the KU Leuven university in the last year construction engineering.
I'm using the finite element software package ANSYS trying to predict the maximum temperature reached during the hydration proces of a concrete element. But I've never worked with ANSYS before so it's completely new for me. I am able to create a mesh and model the element (using the SOLID70-element). I also know how to model the hydration heat at the nodes of the finite elements, but i don't know how I have to account for the heat exchange with the environment. Anyone who has experience with this kind of modelling and is willing to help me?
I guess I have to use the SFA-command for the convection at the topside but I don't know how to model the heatlosses at the sides with shuttering or formwork. Any help with any material properties would be welcome as well.
I would be very grateful if anyone could help me.
Greeting,
Willem Roose
The effect of shuttering can be done in two ways.
1. First model the shuttering itself (say steel) attached to the original structure and the heat transfer will happen as conduction to the shuttering, then the boundary through convection, providing the proper convection coefficient.
2. Provide an apparent equivalent convection coefficient, which can be arrived from experimental study, then by trial and error in the model. This is simpler
