 \mathbf{v}_t = \begin{bmatrix} v_{x,t} \\ v_{y,t} \end{bmatrix}

 ## **Mesh Representation**
 The initial mesh is given by:  
-\[
+$
 \mathbf{M}_0 = \begin{bmatrix} x_1 & y_1 \\ x_2 & y_2 \\ \vdots & \vdots \\ x_N & y_N \end{bmatrix} \in \mathbb{R}^{N \times 2}
-\]
-where each row \( (x_i, y_i) \) represents a mesh point in 2D space.

+where each row $ (x_i, y_i) $ represents a mesh point in 2D space.
 
-Since the mesh is time-dependent, the mesh at time \( t \) is updated based on displacement:
+Since the mesh is time-dependent, the mesh at time $ t $ is updated based on displacement:
 
-\[
+$
 \mathbf{M}_t = \mathbf{M}_0 + \mathbf{d}_t

+Thus, the updated coordinates of the mesh points at time $ t $ are:
 
-\[

 (x_i^t, y_i^t) = (x_i^0 + d_{x,t,i}, y_i^0 + d_{y,t,i}) \quad \forall i = 1, \dots, N

 This formulation describes how the mesh deforms over time due to displacement.

+## Dataset Description: Computational Fluid Dynamics (cfd-data)
+
+This dataset has the same structure as above but here we simulate the movemnet of the water around an rigid object. So we are only simulating Navier-stocks equation.
+
+The displacement field will be all zero as there is no movement of the rigid body.

+mesh = data.input_mesh
+print(mesh.shape)
