        self.mesh = pv.read(fname, file_format='abaqus')
        self.plotter.add_text(fname, 'upper_edge', font_size=10)
        self.mesh['z'] = 20 * np.log10(abs(self.mesh.points[:, 1]) + self.mesh.points[:, 0]**2)
        self.mesh.points[:, 2] = 0
        self.plotter.add_mesh(self.mesh, scalars='z', show_edges=True, lighting=True, show_scalar_bar=False,
                              cmap='viridis')
        actor = self.plotter.add_point_labels(self.mesh.points, list(range(self.mesh.points.shape[0])),
                                              text_color='blue', bold=False, font_size=20, point_size=30,
                                              show_points=False,
                                              shape_color='white', fill_shape=False, shape_opacity=0,
