Reference solution
=====================


Reference quantities and results
-----------------------------------

This is a free dilation problem :math:`(\alpha =1)` of a :math:`(1\times 1)` square.

The displacement along :math:`Y` of the point :math:`C` is then identical to the imposed temperature.

It is thus possible to verify that the displacement curve is indeed a series of rise-fall cycles between temperatures 10 and 17.

We test:


* At point :math:`C`: :math:`\mathrm{DY}(t=\mathrm{1.0s})=\mathrm{DY}(t=\mathrm{2.0s})=\mathrm{DY}(t=\mathrm{4.0s})=\mathrm{15.m}`


* At point :math:`C`: :math:`\mathrm{DY}(t=\mathrm{1.3s})=\mathrm{DY}(t=\mathrm{2.3s})=\mathrm{DY}(t=\mathrm{4.3s})=\mathrm{16.m}`
