Consecutive snapshots of one cell migrating along a rigid obstacle in a 2D simulation. The cell, nucleus and obstacle are visualized by red, green and gray colors, respectively. A blue asterisk denotes a source secreting a chemokine with the secretion rate of $2\times {10}^5\mathrm{mol}/\mathrm{h}\mathrm{\mu }{\mathrm{m}}^3$. The CPU time of this model takes 2.20 s
